One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Problem

If Give an integer N . Write a program to obtain the sum of the first and last digits of this number.

Input

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

Output

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

Constraints

• 1 <= T <= 1000
• 1 <= N <= 1000000

Example

Input:

3
1234
124894
242323

Output:

5
5
5

First and Last Digit CodeChef Solutions in Python

T = int(input())
while T > 0:
    n = (input())
    reverse = n[::-1]
    reverse = int(reverse)
    n = int(n)
    first_digit = reverse % 10
    last_digit = n % 10
    sum = first_digit + last_digit
    print(sum)
    T = T - 1

    int temp=n;
    while(temp/=10){
          len++;
    }
    int last_digit = n%10;
    int first_digit = n/pow(10,len);
    cout << last_digit+first_digit <<'\n';
    }
