Implement a MyQueue class which implements a queue using two stacks.

Guideline:

First implement a stack, there are two ways to do this:

1) static implementation using array.

2) dynamic implementation with linked list.

Implement _push(element)_ and _pop()_ methods, when the stack is working well, create a class *MyQueueClass* and incorporate the idea of stack in it, but the class will have the methods _enqueue(element)_ and _dequeue()_.
How will you do it?
Consider this:

Stack is _Last-In-First-Out(LIFO)_, that's the the push(element) method will add element to the end of the stack and pop() method will remove and return the very last element added.
But Queue is _First-In-First-Out(FIFO)_ the _enqueue(element)_ will also add element to the end like stack's push method but the _dequeue()_ will remove and return the first element added, follow by the second etc.
To implement this Queue principle using two stacks, one way to do this is:

Instantiate two objects of your stack class, add all the elements in the first stack object when user calls the enqueue(element) of the MyQueueClass. But when user calls the dequeue() method you will apply logic here.
Continually pop out the elements in the first stack object into second stack object until the first element is popped out, this first element added, will now be the last element added in the second stack. Pop it out to the user.
That's is queue!

The class is still open to the general public. You can subscribe today by sending me a WhatsApp message. Check my Nairaland signature

Below is described how to find the date of Easter in any year. Despite its intimidating appearance, this is not a hard problem. Note that [x] is the floor function, which for positive numbers just drops the decimal part of the number. For instance [3.14] = 3. The floor function is part of the math module.

C =century (1900’s → C =19)
Y = year(all four digits)
m = (15+C−C4−8C+1325)mod30
n = (4+C−C4)mod7
a = Ymod4
b = Ymod7
c = Ymod19
d = (19c+m)mod30
e = (2a+4b+6d+n)mod7

Easter is either March(22+d+e) or April(d+e−9). There is an exception if d=29 and e=6. In this case, Easter falls one week earlier on April 19. There is another exception if d=28, e=6, and m=2,5,10,13,16,21,24,or39.
In this case, Easter falls one week earlier on April 18. Write a program that asks the user to enter a year and prints out the date of Easter in that year.

Anyone can use frameworks and libraries to develop softwares and applications. There seems to be frameworks and libraries for many applications, this has shifted the attention of some people from understanding the core principles of softwares engineering... algorithms and data structures. There are many frameworks and libraries for virtually anything we want to do, but can they meet all our needs? No, not at all. You would like to program how your software should work the way you want it to work. Then learn to program first. At a professional level what distinguishes one programmer from the others is the knowledge of algorithms and data structures. No matter what you may think this is an absolute truth!

Software companies are riddled with a shocking amount of self-taught amateurs who, despite having programmed on a salary for years, have no grasp of the fundamentals of programming and have no idea what a hash table is, how polymorphism works and how to work with bitwise operations. Don’t be like them! Learn the basics of programming first and then the technologies. Otherwise you risk having your programming skills crippled, more or less, for years, if not for life.
To join the group send me a private message and note I'm not promising to teach you web, mobile or desktop development and as well I'm not promising to make you to be a professional programmer, no not all, and no one person or book or tutorial can do that. To become a proffesional programmer you will have to work hard for some years, years of active and committed programming and project building. My tutorial will certainly pave a way for this journey!
What do I promise?
I'm going to teach you how to program, how divide programming problems into steps and tackle them without fear or visiting the internet. This is the most important thing you need, the rest will become easier if grab these fundamentals

As improbable as it might seem to you, the basic principles of writing computer programs have not changed all that much in the past 15 years. Programming languages change, technologies get modernized, integrated development environments get more and more advanced but the fundamental principles of programming remain the same. When beginners learn to think algorithmically, and then learn to divide a problem instinctively into a series of steps to solve it, as well as when they learn to select the appropriate data structures and write high-quality programming code that is when they become programmers. Once you acquire these skills, you can easily learn new languages and various technologies – like Web programming, HTML5 and JavaScript, mobile development, databases and SQL, XML, REST, ASP.NET, Java EE, Python, Ruby and hundreds more. If you’ve never written a computer program, don’t worry. There is always a first time.
In this tutorial I will teach you how to program from scratch. I do not expect any previous knowledge or abilities. All you need is some basic computer literacy and a desire to take up programming. The rest you will learn from the tutorial.
If you can already write simple programs or if you have studied programming at school or in college, or you’ve coded with friends, do not assume you know everything! Join the group there might be many things you are missing out along the way.

As the world has moved to digital era, where artificial intelligence can take control of the affairs of the world. There is a need to train
programmers who will be the driving forces. Nigerians should not be left behind in this matter, we need experienced programmers who can bring innovations to our country.
Some people keep asking how do I learn programming and what is the best programming language to start with. I have a simple answer to this question:
Start by learning the fundamentals of programming itself and how algorithms work. The programming language to use is really irrelevant at the moment, and no programming language is better than the others, every programming language was developed to meet urgent needs and was created for a particular purpose. Every language has its own advantages and every single one of them could solve most of the problems you'll face in software development process. You should choose the language that you're familiar with. Great softwares are made by great programmers, not by languages they use. So stop wasting your time jumping from one search engine to another to find out the best and lucrative programmming language. I repeat, you can start from any programming language. You must be determined if you really want to learn programming, don't give up easily. Some people have given up before they reach the rewarding apex of programming career. You should love coding, you should love solving problems. Don't love money! Love coding instead. If you love money you may give up before reaching a point where you will start receiving the money. Programming is a lifetime commitment, are you prepared to take it up? I repeat there is no end in coding. You will code until you grow gray hair and die. Are you willing to sacrifice that much time? Programmers are really the most current professionals. they adapt to new technologies like chameleon. If you are determined let's start now! If you have a tendency to give up at a slight encounter of difficult syntax then I would rather recommend a programming language that has simpler approach to syntax, such languages include Python, Java, C#, Ruby and Javascript. I strongly recommend Java. Starting with C or C++ may discourage some who are new to programming because of C strong use of syntax, to be able to solve a simple problem in C, you need to write many lines of code and follow many rules, the beginners who are not determined to learn programming may easily be discouraged. However, if you are determined, not even C can deter you from learning coding.
Resist the temptation to start programming by designing and developing websites and mobile apps, you can never be successful if go on like that. If you start programming like that, you will end up being a laughing stock in a software company. I repeat, don't start programming with building website applications and app development, those things are not bad but you need to start them when you have understood how algorithms work. What is algorithm?

A sequence of steps to achieve, complete some work or obtain some result is called an algorithm. This is how programming is related to algorithms. Programming involves describing what you want the computer to do by a sequence of steps, by algorithms.

Some of your colleagues directly begin programming with Web or mobile applications and databases without knowing what an array, a list or hash table is. Do not envy them! They have set out to do it the hard way, backwards. They will learn to make low-quality websites with PHP and MySQL, but they will find it infinitely difficult to become real professionals. You, too, will learn web technologies and databases, but before you take them up, learn how to program! This is much more important. Learning one technology or another is very easy once you know the basics, when you can think algorithmically and you know how to tackle programming problems.

Starting to program with web applications or/and databases is just as incorrect as studying up a foreign language from some classical novel rather than from the alphabet and a textbook for beginners. It is not impossible, but if you lack
the basics, it is much more difficult. It is highly-probable that you would end up lacking vital fundamental knowledge and being the laughing-stock of your colleagues/peers

Reading books without practising is meaningless! You must spend much more time on writing programs than reading the text itself. It is just like learning to drive: no one can learn driving by reading books. To learn driving, you need to drive many times in different situations, roads, cars, etc. To learn programming, you need to program! Everybody has studied maths in school and knows that learning how to solve maths problems requires lots of practice. No matter how much they watch and listen to their teachers, without actually sitting down and solving problems, they won’t learn. The same goes for programming. You need lots of practice. You need to write a lot, to solve problems, to experiment, to endeavour in and to struggle with problems, to make mistakes and correct
them, to try and fail, to try anew and experience the moments when things finally work out. You need lots and lots of practice. This is the only way you will make progress. So people say that to become a developer you might need to write at least 50,000 – 100,000 lines of code, but the correct number can vary a lot. Some people are fast learners or just have problem-solving experience. Others may need more practice, but in all cases practising programming is very important! You need to solve problems and to write code to become a developer. There is no other way!
