Backspace String Compare
🔥 FULLTIME

Two strings are said to be the same if they are of the same length and have the same character at each index. Backspacing in a string removes the previous character in the string.

Given two strings containing lowercase English letters and the character # which represents a backspace key, determine if the two final strings are equal. Return 1 if they are equal or 0 if they are not. Note that backspacing an empty string results in an empty string.
