This is the simplest task for you (maybe not in programming). But I know you can do it.

You are given two numbers a and b. You have to print the sum of a and b.

Input:

First line of input contains an integer T(T<10), denoting the test case. Each test case contains two integer a and b(0<a,b<10^100).

Output:

For every test case, print the case number, then print the sum of a and b.

 

Sample input and output:
