  2. While either i or j is greater than or equal to 0: a. Initialize two counters skipS and skipT to 0. b. Move i and j backwards, skipping over characters based on the number of backspaces encountered. c. If the current characters of s and t are not backspaces and are not equal, return false. d. If one string is exhausted before the other, ensure that the remaining characters in the other string are all backspaces.
