 Problem

You're given an integer N. Write a program to calculate the sum of all the digits of N.

Input Format

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

Output Format

For each test case, calculate the sum of digits of N, and display it in a new line.

Constraints

Solution:

#include <bits/stdc++.h>

using namespace std;

int main()

{

    int t;

    cin>>t;

    while(t--)

    {

        int n;

        cin>>n;

        int sum = 0;

        while(n!=0)

        {

            int r = n%10;

            sum+= r;

            n /= 10;

        }

        cout<<sum<<endl;

    }

    return 0;

}
