从尾到头打印链表
https://www.nowcoder.com/practice/d0267f7f55b3412ba93bd35cfa8e8035
function printListFromTailToHead(head)
{
let res = [];
while(head){
res.push(head.val)
head =head.next
}
return res.reverse();
}
module.exports = {
printListFromTailToHead : printListFromTailToHead
};
使用while语句从头读链表，当节点不为空时插入，并将节点后移，为空时跳出循环
