Breadth-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’[1]), and explores all of the neighbor nodes at the present depth prior to movi...

Here are some common interview problems where a BFS-style algorithm could work: Binary Tree Level Order Traversal Problem Description: Given a binary tree, return its node values in level order traversal. That is, nodes at each level are visited from left to right, level by level. Applyi...

Given a binary tree, design an algorithm which creates a linked list of all the nodes at each depth (e.g., if you have a tree with depth D, you’ll have D linked lists). Return a array containing all the linked lists. Example: Input: [1,2,3,4,5,null,7,8] 1 / \ 2 3 /...

Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.BFS的:Bread...
