World of gathering data...

Advance Data structure is one thing local man will be learning next semester, and the way he'll focus on it.....

At this point. I throw in the towel. But I achieved something at least.
That last problem is a no go area for me. As for question.4, It's not clear to me.
1. Using java.

public class binaryProblem {
public static int getBase10Value(String num){
    int len = num.length()-1;
    String b = Character.toString(num.charAt(len));
    Integer base = Integer.parseInt(b);
    String newNum = num.replace(b,"" ) ;
    Integer numberInItsBase = Integer.parseInt(newNum,base);
    String numberInBase10 = Integer.toString(numberInItsBase,10);
    return Integer.parseInt(numberInBase10);
  }


  public static void main(String[] args) {
    String a = "102";
    String b = "108";
    String c = "1016";
    int x = getBase10Value(a);
    int y = getBase10Value(b);
    int z = getBase10Value(c);
    System.out.print(x+y+z);
  }
}

Output: 47
Note: The program takes the last number 1016 as base 6.

2. option a is the answer. Because Unix timestamp starts counting at 1st, January, 1979

3.Using java

import java.util.ArrayList;
public class pointBetweenOddNum{
  public static int getNextNumber(int currentIndex, ArrayList<Integer> arr){
    int nextNum = 0;
    if((currentIndex+1) != arr.size()){
      nextNum = arr.get(currentIndex+1);
    }
    return nextNum;
  }
  
  public static ArrayList<Integer> getList(){
    ArrayList<Integer> arr = new ArrayList<Integer>();
    int num;
    for(int i=1; i<1000; i++){
      if(i<100 && i>9){
        arr.add(i/10);
        arr.add(i%10);
      }else if(i>99 && i<1000){
        arr.add(i/100);
        int j = i%100;
        arr.add(j/10);
        arr.add(j%10);
      }else{
        arr.add(i);
      }
    }
    return arr;
  }
  
  public static void main(String[] args) {
    int count=0;
    ArrayList<Integer> arr = getList();
    for(int i=0; i<arr.size(); i++){
      int next = getNextNumber(i,arr);
      int current = arr.get(i);
      int remainder = (current+next)%2;
      if(remainder==0){
        count++;
      }
    }
    System.out.println(count);
  }
}

Output: 1440

4. Not clear. Because all 1000th numbers have 1 in their binary representation.

5.Using java

public class test4 {
  public static int getLength(int num){
    int len = 0;
    for(int i=1; num>2; i++){
      int remainder = num%2;
      if(remainder==0){
        num /= 2;
      }else{
        num=(num*3)+1;
      }
      len=i;
    }
    return len;
  }
  
  public static void main(String[] args) {
    int maxNum,maxNumLength;
    int limit = 421337;
    maxNum = 0;
    maxNumLength = 0;
    for(int i=10; i<limit; i++){
      int len = getLength(i);
      if(len>maxNumLength){
        maxNum = i;
      }
    }
    System.out.println(maxNum);
  }
}

Output: 421336
6. There's time for everything in this life. Please after this competition ends explain how this problem can be solve.

Thank you.

styless:
someone should help me build a blog like DNB Stories, please.

My budget is medium

let's talk.
send me an email @ antonineutron@gmail.com.

I have something for you

That last problem though....

Started at a relatively young age <17

started with the usual HTML,css,basic JavaScript, and PHP. During which I created a web application which enable CBT test to be written online but couldn't deploy it.

But currently am loving Java and developing Android apps.

What is limiting me is no laptop.
Everything I have done is via my phone.

wen are u posting the first challenge

pls it will be better ifu post dey link so that we can click it

who has taken the test?? Did you see your result after the test??

ojonugwaisaac01:
THIS IS NOT TRUE as it conveys a fallacious details

FUL is my great Citadel of learning
Things of such has no place in FUL
It took me of a great delusion even to abscond to the fact that the event throbs mostly in my own department

You have no idea of things that happen in Nigeria universities...


Sex for grade is real.
most of those girls that are lackadaisical with their education are the ones that are involve.
They can greet lecturers in order for them to be noticed.

Stephaustin:
Who told you that ExxonMobil still offers scholarship in Nigeria?

They organized a scholarship program this year....

giwish:
30 questions, 45 minutes mostly gmat questions

snepco or seplat

theultimatep3:
No

regex is the answer

started with 4.65.
currently on 4.52

;.

poor record management.
maybe your paper don lost....

3. Operating System Concepts by Avi Silberschatz
The book I am using.

The spinal cord surgery caused it.
A head surgery need to be done.

no computer science??

How can I go about creating a window base app that can read a user fingerprint(through a fingerprint scanner) and save it.

Ideas and reference to helpful materials will be appreciated.

cool

PatrickOkunima:
In the past, it was possible to become a prof without PhD. Assessment was based on other criteria, like journey publications, etc. But today, to even become a senior lecturer in a Nigerian University, you must have a PhD. Some schools even insist on PhD for Lecturer 1.

so without teaching for at least 3 years in each of the four lecturing positions you can't be a professor??

for instance if the individual is employed as lecturer 1

yes but bring new things to d table

Most federal schools and some states with high application s don't admit under 16.
but with connections and amazing luck she might make it

U re just trying to advertise a product.
All programmers should know dat your problem solving skills is d ultimate

Fragile life
Arafatii orobo dat year WITH JMARTINS
