CodeChef - Reverse The Number

Problem

Given an Integer N, write a program to reverse it.

Input

The first line contains an integer T, the total number of test cases. Then follow T lines, each line contains an integer N.

Output

For each test case, display the reverse of the given number N, in a new line.

Constraints

• 1 <= T <= 1000
• 1 <= N <= 1000000

Solution in Java:

import java.util.*;
import java.lang.*;
import java.io.*;

class Codechef2{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        
        int T = sc.nextInt();
        
        while(T-- > 0){
            long l = sc.nextLong();
            long val = 0;
            
            while( l != 0){
                long v = l % 10;
                val = val * 10 + v;
                l /= 10;
            }
            System.out.println(val);
        }
        sc.close();
    }
}
