Step 4: Dequeue a node N. Process it and set its STATUS = 3 (processed state).

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.
