Given a maze in the form of the binary rectangular matrix, find length of the shortest path in a maze from given source to given destination.
Find the total number of unique paths which the robot can take in a given maze to reach the destination from given source.
Given a N x N matrix of positive integers, find a path from the first cell of the matrix to its last cell.
Given a rectangular path in the form of binary matrix, find the length of longest possible route from source to destination position of the matrix by moving to only non-zero adjacent positions i.e. route can be formed from positions having their value as 1. Note there should not be any cycles in the output path.
Given a maze in the form of the binary rectangular matrix, find length of the shortest path in maze from given source to given destination. The path can only be constructed out of cells having value 1 and at any given moment, we can only move one step in one of the four directions.
