WebWe can easily find the shortest path in the maze by using the backtracking algorithm. The idea is to keep moving through a valid path until stuck, otherwise backtrack to the last traversed cell and explore other possible paths to the destination. For each cell, the following 4 moves are possible: Up – (x, y-1) Down – (x, y+1) Right – (x+1, y) WebNov 7, 2024 · Shortest path solutions for 2D arrays using Breadth-First Search (BFS) Algorithm and Dijkstra's Algorithm.
