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. ...
Slow Pointers ⏰: O(n) 🪐: O(1) var reverseList = function (head) { let prev = null; let curr = head; while (curr) { let next = curr.next; curr.next = prev; prev = curr; curr = next; } return prev; }; which algorithm from ./algorithms.md is used in this solution?
Depth-First Search (DFS) is a graph traversal algorithm used to explore nodes or vertices of a graph deeply before backtracking. Here's how it can be implemented iteratively: 1.Stack Data Structure: In the iterative implementation of DFS, we use a stack data structure to keep track of the...
