DSA - Breadth First Search
What is Breadth First Search? Breadth-first search (BFS) is an algorithm for traversing tree or graph data structures. It starts at the root and explores all the neighboring nodes at the current depth before moving on to nodes at the next depth level. Source Implementation The implementation of BFS may vary depending on the problem. The main idea of BFS is: It has a visited array that collects all elements that have already been visited....
