QUESTION
This is unique path problem from LeetCode https://leetcode.com/problems/unique-paths/.
There is a robot on an m x n grid. The robot is initially located at the top-left corner (i.e., grid[0][0]). The robot tries to move to the bottom-right corner (i.e., grid[m - 1][n - 1]). The robot can only move either down or right at any point in time.
Given the two integers m and n, return the number of possible unique paths that the robot can take to reach the bottom-right corner.
Here is the backtracking solution from tutorialcup https://www.tutorialcup.com/leetcode-solutions/unique-paths-leetcode-solution.htm
...ANSWER
Answered 2022-Jan-14 at 17:15I think there is m*n possibilities which is reduced by one in each recursive step.
No it is reduced by either n or m in each step. So:
