link to the hackerrank question am solving today. https://www.hackerrank.com/challenges/the-birthday-bar/problem?isFullScreen=true

My solution didnt pass all the test cases... had to check the solution. Anticipating your solutions.

Omo questions dey Sha. Make I kukuma take my leave o

Will try to send screenshots from tommorow and possibly the approach I use in tackling the question.

Najdorf:
Nice work OP. Please try and share some of the DSA problems you deal with daily so that we can also have a go at them

So guys, couldn't drop an update yesterday cos we have not been having light for the past few days. I solved an another hackerrank question today.

I also applied for a free DSA bootcamp. The bootcamp requires some knowledge of OOP. We were given two very basic test questions on hackerrank. It happened that they were questions have done before. Literally solved the first questions in seconds only to get stuck at the second question despite the fact that I have solved it before.



Spent over an hr staring at the screen after getting compilation error only to discover that I used arr[I] instead of arr.get(i) for ArrayList in java. JavaScript syntax really messed with my head. I guess that's one of the disadvantage of learning multiple languages at once.

I also watched some video on improvements of quick union; weighted quick union and compression of paths.

I have not read head first Java today. Will probably do that now then rest for some time b4 I hit the books again.

The battery I was using then was very bad, the charger was bad too- television kind of laptop.

When Nepa takes light my system goes if too...been using it like that for months cos I wanted to save up an buy a double cell battery which will last me hrs and an original charger.

Because the charger was bad too, I used my roommates charger....my laptop was a Dell laptop but I was switching between Dell and HP chargers. My roommates warned me though.

One day I woke up an my laptop refused to on.

TastyFriedPussy:
I've seen alot of people on this section complain about their laptops crashing after they've gone far in the learning process and them having to wait to get another laptop or pay huge monies to fix it and that shíts scares me lol. I can't afford anything happening to my laptop after knowing the kind of suffer I had to suffer to get it, because I fit die
So what's makes people laptop crash and how can one avoid such

1.)What are the things I need to avoid doing in order to prevent my laptop from crashing
2.) Does the laptop crashing means it is damaged for good or can still be fixable
3.) I heard that windows OS are more prone to crashing than Linux, how true?

@AlchemyOfCodes

Not making any progress with react after running into a bug. My data refused to fetch...Get Error 403 checked my url and also logged in to rapid API for authentication still no change. So I literally spent 1hr trying to fix bugs in react today

Omo. DSA is hard Sha. Watched a video for 5 mins in 30 mins and have already gave my sef an assignment to watch at least 4 YouTube videos on the concept. Only God knows when I will finish the course...but I won't exceed my daily limit of 30mins.

Read head first Java and I learnt about how constructors can be useful in initializing an object state before the object is created to avoid issues of having objects without instance variables that are very important. Just touched it surface level though cos I have to stick to 5 pages a day.

Did some R programming too. Initializing variables with -> and escaping strings and printing it out using the cat() method instead of print() cat sounds wierd to me though.

Ok guys, I solved an hackerrank question today using nested loops, would have loved to optimize the run time a bit but no time. Sometimes I wonder if all solutions can be improved from say from O(n^2) to maybe O(logn/n) using recursion?

Well I think some problems can't really be optimized, there is a particular one I read in grokking algorithm, can't remember properly about distance; maybe shortest distance to deliver goods to an end point where we have to check every available routes; can't remember... would have loved to re-check but no time.

My question is how one can identify such problems so we don't spend unnecessary time thinking of how to optimizing codes....anyways am not sure of what am saying sef.

Am not into mobile app development. But I think flutter, React Native, Kotlin and others are used for mobile app development. Yes, about the accountability ish. I just joined a WhatsApp group where students combining learning skills and schooling help each other in the aspect of time management.

yinkbell:


Sorry about that. I have been following your progress on this journey. I thank God for you that you were able to get another laptop. I saw your passion and zeal to learn so fast which is good.

You are only accountable to yourself. Why can't you ask other people who are in this path to join you so that you will be accountable to one another.

If you don't code or do any task in a day, the other people will like to know your reasons and motivate one another not to relent.

Meanwhile, I got my Laptop last week; a fairly used one. Core i5, 8gig RAM and 500gig.
How do I commence if I am to learn mobile app development? Though I am still thinking of learning other stuffs which does not involve coding.

Which programming language one will use to learn mobile app? Thanks so much.

Faulty battery, kinda a television kind of laptop and using incompatible chargers.

yinkbell:


What made your laptop crashed?

Yo guys! met my reading target today. Solved an hackerrank question....my code passed just one test case...had to check the answer when I was running out of time.

Did 30 mins of DSA course today, watched a video about cracking DSA and the person advised that writing stuffs down as you learn DSA is a great way of mastering it.

so I got a book to jot some stuffs down.

Learnt how to fetch data from Rapid APIs using axios. Ran into another bug..... something that has to do with useEffect.

Yeah! Will also be adding the R language to my arsenal. Just discovered that I will be offering a practical statistical course on it this semester. Trying to take things slow and steady... I learnt how to print and comment in R language today on sololearn.

I have no intentions of halting my programming journey...have come way too far to stop and programing is one thing I really enjoy doing

I have decided to drop the zuri bootcamp, front end meta tutorial so as to focus on practicing react and DSA for 3hrs daily only.
Henceforth, will be reading just 5 pages of Head first Java daily ... dropped secret of Js Ninja

30mins of my algorithm course on Coursera daily.

An hackerrank question daily....1 hr max spent on figuring out the solution b4 checking the solutions of others.

And the rest will be spent on honing my front end skills.

Then after the school break, Will go back to coding without borders......time limit.

The rest of my day will be spent jacking cos nothing dey my head asides coding like this.

The goal is to remain consistent even if to has to be 30min of coding everyday.

I am writing this epsitle cos I know some student may be in my shoes right. You don't have to sacrifice your grades for skills. With hard work and discipline, everything is possible.

I just want to thank everyone that havecontributed to the thread so far......Hanania, Qtguru, tensa..., ChukwuEbuka and others.

This is the longest ever streak have gone on consistency when it comes to programming...sometime when I want to chill a bit and I remember I have to update this thread on what programing concepts have learnt... I just have to succumb.


I will try to drop updates on my programming journey everyday....if school doesn't stress the hell outta me. I'm still commited to my goal of becoming a world-class programmer and thereafter have an opportunity to get to work at Google.

From my research on quora, there was a particular job listing on Amazon for software developers which allows applicants with bionfomatics and computational biology degrees.

Am in my penultimate year, working very hard now will afford me the opportunity of having my masters in computational biology...will boost my CV a bit.....

Ok guys back to serious business. Will have to reset some of my goals again. As we all know the ASUU strike is coming to an end....and I have no intentions of sacrificing my accademics for coding this semester...my grades suffered last semester as a result.

I've made my research and I found that it is possible to achieve academic excellence while coding on the side. At least from the testimony of a BGS who is also from the biological sciences like me.

So I will be making some serious decisions that will slow down my growth in programming and also decisions that will shape and re-shape my future.

I've also watched the first one hour YouTube 2.0 tutorial. Had to stop when I ran into bugs again. Have not been following up on my reading Target and I know why. Have a lot on my hands that am feeling burnt out already.

Ok guys seems I made an error of pasting one of my messages in another thread. Anyways I was able to solve two hackerrank question today. No one..wrote the first one independently while I had to check answers to the second one.

Actually I think I've got too accustomed to for loops that the first thing that comes to my mind when I see a DSA question involving loops is the for loops.

Couldn't even attempt the second question cos I was fixated on for loops forgetting that while loops are ideal for loops that we don't have an idea of when it's going to terminate.

Same thing for if else statement forgetting we have the switch case. I've Always googled the syntax for switch case until recently after completing the calculator project.

So guys, I was able to watch the youtube 2.0 tutorial up to 40 mins before bugs did it thing again. I really learnt a lot and have not even started yet. Things like reading official documentations on the go....learnt a bit about material UI by reading documentations. Frameworks are really powerful, the fact that you can deal with mobile responsiveness with just few lines of codes is awesome.

I was also able to solve another hackerrank question today thougn my syntax was a bit long. Saw someone else solution which was just in two lines of java. some people are really good in this programming thing.

Will try to implement the calculator ish this night, I hope it will finally work. Thanks once agian @Chukwuebuka65

I have set a new target of 30mins per day for my DSA course cos my learning is not really structured

So guys, didn't do much today. Light wasn't stable. So I watched 40 mins of the YouTube 2.0 tutorials before bugs did it thing again. Really learnt a lot...material UI and how to read documentations on the go.

I was also able to solve another hackerrank question today... quite easy though...but my syntax was a little bit long. I was shocked when I saw someonelse solution which was just 2 lines long in Java....some people are just crazy in this programming thing.

Meanwhile just discovered there is an entirely new section for data structures. Been solving alogrithm questions all this while. Decided to take a peep into the data structures question. I ran out as fast as I came in ...still have a long way to go in this DSA thing

Anyways e be like say ASUU won call off strike ooo. Me wey be say na only coding dey my head like this. Have to hit the books again.

Made some adjustments to schedule...might have to drop the zuri course for the mean time. Someone once said coding 10 mins everyday is better than coding 4 hrs a week. Any how this strike turns out...I won't stop coding.

Omo! Couldn't do anything today. No light and have been sleeping all day. Had to go charge my phone outside for a token. Hope they bring the light soonest.

Will spend the rest of the night reading docs, practicing on sololearn, going through the DSA course, and of course checking algorithm questions on hackerrank.

Sure. Sent you a PM.

Darealudeme:
Welldone bro, been following your journey since Today began. Could I get your profiles (esp GitHub, LinkedIn and Twitter) for a follow. WhatsApp' contact would be fine as well. If you comfortable with sharing your number online

Don't wait. Just begin!

francium001:
Good day and happy Sunday to you all

I have been going through this thread for quite awhile now and I am impressed with the motivation I am getting to start my journey into web development but I have a question to ask and it's thus, I don't have a laptop or desktop (though I am planning on getting one soon) for now just my Android phone, will I be able to far into learning web development with just my Android phone or should I wait until I get a laptop?

I have gotten the W3school app, sololearn app and other apps that I think I can learn from. I have been learning from those apps though not consistent due to my daily engagements but it seems as if I am not making any progress and that I am just wasting time and might restart relearning all I am learning now when I get a laptop?

Please Bosses in the house and those who might have started off with just an Android phone should let me know if I should wait or continue.

Sorry for the long epistle, I am just trying to make my situation understandable.

Thanks will give it a try.

chukwuebuka65:
You should have an array where you push the result of every calculation. Then add a click event on the button that will run a function to update ur state with last item added to the array.

I wanted to host the project before and drop link here, but with the look of things I won't bother again until I get the issue fixed.

Meanwhile, me have moved on oo. I cannot come and kill myself. Started a tutorial on YouTube 2.0 clone. I hope it doesn't end up in the trash like the e-commerce project. Cos e don dey show me shege already...bugs. I will still do the E-commerce project though.

My own bugs majorly comes from installing dependencies and conflicting dependencies. This is one reason I don't like react for, well it's not react fault though..


Will try to solve an hackerrank question today even if it is just to look at solutions. And then my reading target and of course the tutorial am currently on .... If Nepa cooperate

I checked the web for similar project. I couldn't found any with the history button. I did find one though on sololearn but the logic was implemented in JavaScript.

Please seniors in the house, if there is anyway I can get past this issue please do share. And I don't mind pasting some of my spaghetti code here ; D Thanks.

3) Thirdly I kind of found an easy way out. Just replicate the state somewhere else on the screen. As the user is typing, the state will render somewhere else. Like when a user type 2+2. The current state which is the 2+2 will be repeated somewhere on the screen so the user can always check previous state.

The history can only be deleted with the AC button. But again using this method means am not going to have my history button which is one functionality I would love to have.

2) I tried using the logic operator && to check if the history button was clicked. If true it will render the current state. I just duplicated the current state in a div tag.This is quite stupid of me though

First, every possible way I tried to check if the button was clicked threw an error... probably don't know how to check

Secondly, since am replicating the current state. That means when I click the AC the button, my current state will be null. Clicking on the history button will render null as well which is definitely not what I intend.

Here are some of the steps I tried with no luck

1) I tried tracking the state and storing it in a "store object" added to my list of ACTIONS- since am using useReducer hooks. An onclick event was then added to my History button to fire the rendering of the store obj when the history button is clicked.


Honestly, I think this should work if I did the right way. But because am pretty new to react coupled with the fact that the useReducer hook syntax was all over the place, am not so sure I did the right thing.

But the problem started after I tried to implement the history button. I spent hours trying until I finally gave up and moved on to another project.

Now the issue is creating an history button that goes back to a previous state. Say I punched 2+2 and get the result, clicked on the AC/clear button- the history button should return 2+2.

Yean guys! I finally replicated the project without looking at the tutorial. I did some googling and I also checked some code snippets before completing the project.

About the extra features, I decided to add root operation and an history button to go back to previous state. The root operation was quite easy, so I implemented it in no time.

Out of boredom, I watched some PHP tutorial on Zuri, also download NET NINJA tutorial on PHP and MYSQL to supplement the course. Learning PHP made me realize that programming languages are the same; at least the basic concepts of loop, functions, variables and so on. The only difference is the syntax. I find it very weird that variables in PHP global scope cannot be accessed inside a function without using the global keyword - then why the hell is it called global scope then?

I also watched some introductory video on meta course for front-end. This is one course am going to finish, because the instructors have been superb so far. Also watched some videos on the java DSA course.

At this point am tired..... though have not met my reading target for today.... will have to cool my heads off with a movie; probably rings or power or ANIKULAPO-really hope it is worth the hype though.

Below is a snapshot of the calculator app

I was quite busy today. I have started the calculator project and I have designed the css aspect, also created the actions object, the useReducer hook is still in progress. Will post a snapshot below.

Meanwhile, I had to revise some css concepts like grid and flex during the course of the video. I am still looking for a tutorial or book that teaches the nitty-gritty of css. Things like when to use vh, rem, px, positioning, and others.

I was able to solve two hackerrank questions today even though I promised to stick to one. I have to admit that I still had to check the solution when my code was not passing all the test cases. I am just happy that am beginning to think like a programmer as some people's solutions followed my exact thought process.

I tried to increase the hackerrank question I solve per day to two, but I was only able to solve one today. Even the one sef didn't pass all the test case but I was able to figure out the issue.

I can't understand the logic behind the second hackerrank question till now even after checking two solutions.

I will have to still stick to one hackerrank question per day pending the time am very very comfortable with Java.

Ye! Was able to complete my zuri tasks on time. So I have the next couple of days to my self. The deadline of the remaining tasks are week(s) away
