문제 Design your implementation of the linked list. You can choose to use a singly or doubly linked list. A node in a singly linked list should have two attributes: val and next. val is the value of the current node, and next is a pointer/reference to the next node. If you want to use the doubly linked list, you will need one more attribute prev to indicate the previous node in the linked list. As..

문제 Given a binary tree root and a linked list with head as the first node. Return True if all the elements in the linked list starting from the head correspond to some downward path connected in the binary tree otherwise return False. In this context downward path means a path that starts at some node and goes downwards. 이진 트리 루트와 헤드를 첫 번째 노드로 하는 링크된 목록이 제공됩니다. 머리글에서 시작하는 링크된 목록의 모든 요소가 이진 트리에 연..

문제 Given the head of a singly linked list, return the middle node of the linked list. If there are two middle nodes, return the second middle node. head단일 연결 목록이 주어지면 연결 목록 의 중간 노드를 반환합니다 . 두 개의 중간 노드가 있는 경우 두 번째 중간 노드를 반환 합니다. 예시 Example 1: Input: head = [1,2,3,4,5] Output: [3,4,5] Explanation: The middle node of the list is node 3. Example 2: Input: head = [1,2,3,4,5,6] Output: [4,5,6] Explana..
