If you are looking for linked list problems or coding interview resources then you have come to the right place. In the past, I have sharedbest coding interview books,courses,websites, and100+ coding problemsand today, I am going to share 20 Leetcode problems you can solve to get better ...
Given a singly linked list, group all odd nodes together followed by the even nodes. Please note here we are talking about the node number and not the value in the nodes. You should try to do it in place. The program should run in O(1) space complexity and O(nodes) time complexity....
The space complexity is O(1). 2. Complexity of Deletion Operation All deletion operations run with a time complexity of O(1). And, the space complexity is O(1). Why Circular Linked List? The NULL assignment is not required because a node always points to another node. The starting point...

Given a singly linked list, group all odd nodes together followed by the even nodes. Please note here we are talking about the node number and not the value in the nodes. You should try to do it in place. The program should run in O(1) space complexity and O(nodes) time complexity...
234. Palindrome Linked List Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 一刷 题解:如果不修改input(即reverse它的下一半的话)是不可能达到O(n) time and O(1) space complexity的。
Assume N represents the number of nodes in the linked list. Time Complexity: O(N) because each node is visited exactly once. Space Complexity: O(1) because the algorithm uses a constant amount of extra space for counters. Pages 1,056 Loading Home Loading 01 Matrix Loading 2 Pointer ...
2.1. Brute Force – O(n^2) Time Complexity With this algorithm, we traverse the list using two nested loops. In the outer loop, we traverse one-by-one. In the inner loop, we start from the head and traverse as many nodes as traversed by outer loop by that time. ...
