Multiply Strings

Explore how to multiply two non-negative integers represented as strings by implementing an algorithm that simulates manual multiplication. Understand the problem constraints and optimize your solution to run in O(m x n) time with O(m + n) space, helping you handle large inputs beyond standard integer limits.

Statement

Given two non-negative integers, str1 and str2, represented as strings, return the product of these integers, result, which is also ...
