Problem: Multiply Strings

med
30 min
Explore how to multiply two numbers given as strings without converting them directly to integers. Learn to implement an optimal algorithm with O(m x n) time complexity and O(m + n) space usage, deepening your understanding of string-based arithmetic in coding challenges.

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.
  • 1≤1 \leq str1.length, str2.length ≤200\leq 200
  • No leading 00 in str1 or str2
