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.

Accepted Answer

Implement a function to compute the sum of two large integers given as strings.

Convert the input strings to integers and add them digit by digit from right to left, considering carry over.
Handle cases where one number is longer than the other by padding with zeros.
Return the final sum as a string.
