To solve “1367. Linked List in Binary Tree” in JavaScript, we use Depth-First Search (DFS) to traverse the binary tree and check if the linked list exists as a downward path starting from any node. We implement a recursive function to match the linked list with the tree nodes. If a match is found, we return true.
This post explores the solution to Leet Code problem 3217, which involves deleting nodes from a linked list that are present in a given array. Learn step-by-step how to approach and solve this problem efficiently.
In today’s LeetCode Problem of the Day (POTD), we tackle Problem 2028: Find Missing Observations. This problem challenges us to reconstruct missing dice roll results given the mean and a partial list of observations. We’ll explore an efficient approach using math and logic to solve the problem within the given constraints. A must-read for anyone practicing array manipulation and problem-solving on LeetCode!
