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_06 {
public int[] reversePrint(ListNode head) {
Stack<ListNode> stack = new Stack<ListNode>();
ListNode temp = head;
while (temp != null) {
stack.push(temp);
temp = temp.next;
}
int size = stack.size();
int[] print = new int[size];
for (int i = 0; i < size; i++) {
print[i] = stack.pop().val;
}
return print;
}
}
