Sum of Big Integers Problem Statement

Given two integers represented as strings, 'NUM1' and 'NUM2', compute and return their sum.

Input:

T NUM1 NUM2 ...

Output:

Sum of NUM1 and NUM2 for each test case

Constraints:

1 <= T <= 10000
1 <= |NUM1| <= 10⁵⁰
1 <= |NUM2| <= 10⁵⁰
Where: T is the number of test cases, and NUM1 and NUM2 are the numbers given as strings.

Accepted Answer

Using Strings. Let us store ‘NUM1’ and ‘NUM2’ as strings rather than storing them as integers. We will calculate the sum as follows: We will add zeroes before the smaller string among ‘NUM1’ and ...
