Problem: Multiply Strings

Medium
30 min
Understand how to multiply two non-negative integers given as strings by building an efficient algorithm. Explore the problem constraints, develop your solution strategy, and implement it to achieve optimal time complexity, boosting your coding interview skills.

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
