Breadth first search problems

WebBreadth–first search (BFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the tree root (or some arbitrary node of a graph, sometimes referred to as a 'search key') and explores the neighbor nodes … WebBreadth First Search (BFS) and Depth First Search (DFS) are two of the most common strategies employed in problems given during an interview. Proficiency in these two algorithms will allow you to solve (in our estimation) at least two-thirds of tree and graph problems that you may encounter in an interview. Additionally, a surprising number of ...
