Multiply Strings

Understand how to multiply two non-negative integers represented as strings without converting them directly to numbers. Explore building the product using O(m x n) time and O(m + n) space complexity. Practice implementing this pattern to solve similar coding interview problems efficiently.

Statement

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

Constraints:

  • str1 and str2 consist of digits only.
  • 11 \leq
