{
    // * Initializing variables
    int numberOfTestCases, n, remainder, sum;

    // * Accepting the number of test cases
    cin>>numberOfTestCases;

    // * Executing each test case one by one
    while(numberOfTestCases--)
    {
        // * Accepting the integer n
        cin>>n;

        // * Initializing remainder and sum to 0
        remainder = 0, sum = 0;

        // * Looping while n is not 0
        while(n!=0)
        {
            // * Finding the last digit of n
            remainder = n%10;

            // * Removing the last digit from n
            n = n/10;

            // * Adding it to the sum
            sum += remainder;
        }

        // * Displaying the sum of all digits
