We are nearing the end of the useful Leetcode questions to cover.
Hope you’re excited.
Since DP seems to be a problem for many, thought I’d throw more of these to finish up.
This question can be found as Leetcode 62. Unique Paths.
Problem
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.
The test cases are generated so that the answer will be less than or equal to 2 * 109
.
Example 1:
Input: m = 3, n = 7
Output: 28
Example 2:
Input: m = 3, n = 2
Output: 3
Explanation: From the top-left corner, there are a total of 3 ways to reach the bottom-right corner:
1. Right -> Down -> Down
2. Down -> Down -> Right
3. Down -> Right -> Down
Constraints:
1 <= m, n <= 100

Before you leave, there is one final thing I would like to talk about. As you may know, I’m a university student, about to graduate in May of this year. After graduation, I will be looking for work. If you have any leads, I would really appreciate introductions. My resume is here and you can find my LinkedIn profile here. Being a startup, the company I’m with currently can’t provide Visa Sponsorship (same for most of the recruiters that reach out to me through LinkedIn). Any help in this matter would be greatly appreciated.
