 ANSWER:-

#include<iostream>

using namespace std;

int main(){

    int test;

    cin>>test;

    while(test -- ){

        int n,rem, sum = 0;

        cin>>n;

        while(n>0){

        rem = n % 10;

        sum += rem;

        n /= 10;

        }

        cout<<sum<<endl;

    }

    return 0;

}
