844 - Backspace String Compare.

Easy

Given two strings s and t, return true if they are equal when both are typed into empty text editors. '#' means a backspace character.

Note that after backspacing an empty text, the text will continue empty.

Example 1:

Input: s = “ab#c”, t = “ad#c”

Output: true

Explanation: Both s and t become “ac”.

Example 2:

Input: s = “ab##”, t = “c#d#”

Output: true

Explanation: Both s and t become "".

Example 3:

Input: s = “a#c”, t = “b”

Output: false

Explanation: s becomes “c” while t becomes “b”.

Constraints:

• 1 <= s.length, t.length <= 200
• s and t only contain lowercase letters and '#' characters.

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