REVERSE A STRING

Description:

"If an Integer N, write a program to reverse the given number. Input The first line contains an integer T, total number of testcases. Then follow T lines, each line contains an integer N. Output Display the reverse of the given number N. Constraints 1 <= T<= 1000 1 <= N <= 100000 " Test Case 1 Input (stdin) 3 12345 31203 2123 Expected Output 54321 30213 3212 Test Case 2 Input (stdin) 2 78657 100034 Expected Output 75687 430001

Program :

#include <stdio.h>

int main()

{

  int t;

  scanf("%d",&t);

  while(t--)

  {

    int num;

    scanf("%d",&num);

    int rev=0;

    while(num)

    {

      rev=rev*10+num%10;

      num/=10;

    }

    printf("%d",rev);

    printf("\n");

  }

  return 0;
