In a square maze, we can have multiple steps from ‘s’ to reach ‘e’ with one place that can only be visited once. Example:   The problem: ➢ Input: an integer followed by the maze. ➢ Output: total number of unique steps. (no need to print the unique steps) ➢ Task: Design an algorithm in pseudocode/code to print the total number of unique steps using a backtracking algorithm.
