Depth first search is a graph search algorithm that starts at one node and uses recursion to travel as deeply down a path of neighboring nodes as possible, before coming back up and trying other paths. const {createQueue} = require('./queue'); func…
There are generally two methods to write DFS algorithm, one is using recursion, another one is using stack. (reference from Wiki Pedia) Pseudocode for both methods: A recursive implementation of DFS: procedure DFS(G,v): label v as discovered for all…
