| Shortest Path in a Grid | | You are given a 2D array of numbers (array of array of numbers) representing |
| | | a grid. The 2D array contains 1's and 0's, where 1 represents an obstacle and |
| | | 0 represents a free space. |
| | | |
| | | Assume you are initially positioned in top-left corner of that grid and that you |
| | | are trying to reach the bottom-right corner. In each step, you may move to the up, |
| | | down, left or right. Furthermore, you cannot move onto spaces which have obstacles. |
| | | |
| | | Determine if paths exist from start to destination, and find the shortest one. |
| | | |
| | | Examples: |
| | | [[0,1,0,0,0], |
| | | [0,0,0,1,0]] -> "DRRURRD" |
| | | [[0,1], |
| | | [1,0]] -> "" |
