Shortest Clear Path
Swipe to start coding
Given an n x n matrix grid, which contains of 0 and 1 only. Find the length of the shortest path in the matrix, which starts with grid[0][0] and ends in grid[n-1][n-1], and next conditions are satisfied:
- All cell of the path are
0 - All the adjacent cells of the path are connected 4-directionally.
The length of such a path is number of visited cells.
If there is no clear path, return -1.
Example 1
Input: n=3, grid = [[0, 0, 0],[1, 0 ,0],[1, 1, 0]]
Output: 5
Example 2
Input: n = 3, grid = [[0,1,0],[0,0,1],[1,1,0]]
Output: -1
