  Problem:-

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

Input

The first line contains an integer T, total number of testcases. 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

Sample Input 1 

4
12345
31203
2123
2300

Sample Output 1 

54321
30213
3212

Code:-

#include <iostream>
using namespace std;

int main() {
int t;
cin>>t;
while(t--)
{
int n,reverse_num=0;
cin>>n;
while(n!=0)
{
int r=n%10;
n=n/10;
reverse_num=reverse_num*10+r;
}
cout<<reverse_num<<endl;
}
    // your code goes here
    return 0;
}
