WebNov 22, 2024 · source: leetcode.com. Let us suppose that a fast pointer and a slow pointer both point to the head of the list. The slow pointer travels the linked list one node at a time whereas the fast pointer travels the linked list two nodes at a time. If the faster pointer and the slow pointer point to a same node, then the linked list has a loop. WebThe two pointer technique is a near necessity in any software developer's toolkit, especially when it comes to technical interviews. In this guide, we'll cov...

Fast & Slow Pointers — A Pattern for Technical Problems

WebAs we know that slow pointer increments by one and fast pointer increments by two. In the above example, initially, both slow and fast pointer point to the first node, i.e., node 1. The slow pointer gets incremented by one, and fast pointer gets incremented by two, and slow and fast pointers point to nodes 2 and 3, respectively, as shown as below: WebApr 24, 2024 · The typical algorithm using fast and slow pointers is LeetCode 141.
