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)。
示例 1:
输入:head = [1,3,2]
输出:[2,3,1]
class Solution {
public int[] reversePrint(ListNode head) {
LinkedList<Integer> stack = new LinkedList<Integer>();
while(head != null){
stack.addLast(head.val);
head = head.next;
}
int[] res = new int[stack.size()];
for(int i =0;i<res.length;i++){
res[i] = stack.removeLast();
}
return res;
}
}
