题解 | #从尾到头打印链表#

tip：head本身就是一个实体，形如{val: "1234", next: headNext}

/*function ListNode(x){
    this.val = x;
    this.next = null;
}*/
function printListFromTailToHead(head)
{
    let array01 = [];
    while(head) { // 思考为什么不是head.next
        array01.push(head.val);
        head = head.next;
    }
    return  array01.reverse();
    // write code here
}

module.exports = {
    printListFromTailToHead
};
