Solution: Backspace String Compare

Explore how to use the two pointers approach to determine if two strings, including backspace characters, produce the same final output. This lesson guides you through an efficient comparison method that avoids reconstructing the strings, achieving O(n) time and O(1) space complexity.

Statement

Given two strings s and t, return true if they produce the same result when typed into an empty text editor, where '#' represents a backspace character. Applying a backspace on an empty editor leaves it unchanged.

Note: Can you solve it in O(n)O(n) time and O(1)O(1) space?

Constraints:

  • 11 \leq ...
