Sum of Big Integers Problem Statement

Given two integers, NUM1 and NUM2, as strings, your task is to compute and return the sum of these numbers.

Input:

The first line contains an integer T, the number of test cases. The next T lines each contain two space-separated strings NUM1 and NUM2 representing large integers.

Output:

For each test case, output the sum of NUM1 and NUM2 as an integer.

Example:

Input:
T = 2
NUM1 = "123456789123456789", NUM2 = "987654321987654321"
NUM1 = "111111111111111111", NUM2 = "222222222222222222"

Output:
1111111111111111110
333333333333333333

Constraints:

• 1 ≤ T ≤ 10000
• 1 ≤ NUM1 ≤ 10^50
• 1 ≤ NUM2 ≤ 10^50
• Time Limit: 1 sec

Note:

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