Can we use longest path algorithm on a graph to determine the longest length ladder needed for the player? Possible approach would be (Comment if I am not right in the approach):
1. DFS in 4 directions (North, South, West & East)
2. Construct path decomposition from start to finish while traversing from start to finish in all four directions as in step 1.
3. Apply DP to find the path decomposition to find the longest path.

Look up wikipedia on longest path traversal
