Solution: Backspace String Compare

Explore how to apply the two pointers technique to solve the Backspace String Compare problem efficiently. This lesson teaches you to traverse two strings from right to left, managing backspace operations without extra space, and compare the resulting visible characters. Understand both the algorithm and its optimal time and 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 ...
