js剑指 Offer 06. 从尾到头打印链表

输入一个链表的头节点,从尾到头反过来返回每个节点的值(用数组返回)。

输入:head = [1,3,2]
输出:[2,3,1]
/**
 * Definition for singly-linked list.
 * function ListNode(val) {
 *     this.val = val;
 *     this.next = null;
 * }
 */
/**
 * @param {ListNode} head
 * @return {number[]}
 */
var reversePrint = function(head) {
    
    
    // if(head == null){
    
    
    //     return [];
    // }
    // if(head.next == null){
    
    
    //     return [head.val];
    // }
    let temp = head;
    let res = [];
    while(temp){
    
    
        res.unshift(temp.val);
        temp = temp.next;
    }
    return res;
};
