WebNote that in BFS, all cells having the shortest path as 1 are visited first, followed by their adjacent cells having the shortest path as 1 + 1 = 2 and so on… So if we reach any node in BFS, its shortest path is one more than the shortest path of the parent. WebBreadth-first search ( BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.

Finding Shortest Paths using Breadth First Search

WebGiven a graph, we can use the O(V+E) DFS (Depth-First Search) or BFS (Breadth-First Search) algorithm to traverse the graph and explore the features/properties of the graph.
