To be honest, this question is a little too simple. Thanks to the question guaranteeing that you won’t be given the tail node of a Linked List, there aren’t even any edge cases to handle, so the solution comes in at a whopping 2 lines.

In this LeetCode problem, we’re given a Linked List, and asked to determine whether or not it (or rather, its values) represents a palindrome. Revision point 1: A linked list is a data structure that consists of two properties; next which points to the next node in the list, and…

In this LeetCode problem, we’re given a string str and an integer k, and asked to return the longest substring of str, which is made up only of characters that appear k or more times. In other words, given the string ‘aabbbcccc’ and a k value of 3, the longest…
