Sum of Big integers.

You have been given two integers ‘NUM1’ and ‘NUM2’ as a string. Your task is to print the sum of both the numbers.

Input Format:

The first line contains a single integer ‘T’ representing the number of test cases. The 'T' test cases are as follows: 

The only line of each test case contains two space-separated integers ‘NUM1’ and ‘NUM2’ representing two integers whose sum you need to return. As numbers are pretty large ‘NUM1’ and ‘NUM2’ will be provided as strings.

Note:

You do not need to print anything; it has already been taken care of. Just implement the function.

Output Format:

For each test case, print the sum of two numbers.

Constraints:

1 <= T <= 10000
1 <= NUM1 <= 10^50
1 <= NUM2 <= 10^50

Where ‘T’ is the number of test cases. ‘NUM1’ and ‘NUM2’ are the numbers whose sum you have to compute.
