## 数组转换成链表 ```typescript interface LinkedList { value: Number | null; next: LinkedList | null; } const toLinkedList = (array: Number[]): LinkedList => { let linkedList: LinkedList = { value: null, next: null, }; const endLength = array.length - 1; for (let index = endLength; index >= 0; index--) { linkedList = { value: array[index], next: index === endLength ? null : linkedList, }; } return linkedList; }; ``` ## 反转单向链表 ```typescript interface LinkedList { value: Number | null; next: LinkedList | null; } const reverseLinkedList = (LinkedList: LinkedList) => { let preNode: LinkedList | null = null; let curNode: LinkedList | null = LinkedList; let nexNode: LinkedList | null = LinkedList.next; while (curNode) { curNode.next = preNode; preNode = curNode; if (nexNode == null) break; curNode = nexNode; nexNode = nexNode.next; } return curNode; }; ``` ## 使用链表实现队列
