Unique Paths– LeetCode Problem
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:
![Unique Paths LeetCode Programming Solutions | LeetCode Problem Solutions in C++, Java, & Python [💯Correct] 2 robot maze](https://assets.leetcode.com/uploads/2018/10/22/robot_maze.png)
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
Unique Paths– LeetCode Solutions
Unique Paths in C++:
class Solution { public: int uniquePaths(int m, int n) { vector<int> dp(n, 1); for (int i = 1; i < m; ++i) for (int j = 1; j < n; ++j) dp[j] += dp[j - 1]; return dp[n - 1]; } };
Unique Paths in Java:
class Solution { public int uniquePaths(int m, int n) { int[] dp = new int[n]; Arrays.fill(dp, 1); for (int i = 1; i < m; ++i) for (int j = 1; j < n; ++j) dp[j] += dp[j - 1]; return dp[n - 1]; } }
Unique Paths in Python:
class Solution: def uniquePaths(self, m: int, n: int) -> int: # dp[i][j] := unique paths from (0, 0) to (i, j) dp = [[1] * n for _ in range(m)] for i in range(1, m): for j in range(1, n): dp[i][j] = dp[i - 1][j] + dp[i][j - 1] return dp[-1][-1]
