WebJun 16, 2024 · The Breadth First Search (BFS) traversal is an algorithm, which is used to visit all of the nodes of a given graph. In this traversal algorithm one node is selected and then all of the adjacent nodes are visited one by one. After completing all of the adjacent vertices, it moves further to check another vertex and checks its adjacent vertices ... Web63 lines (49 sloc) 1.27 KB. Raw Blame. import java. util.
