用字符串对比不就行了
/* * function ListNode(x){ * this.val = x; * this.next = null; * } */ /** * * @param head ListNode类 the head * @return bool布尔型 */ function isPail( head ) { // write code here let str = ''; let strReverse = ''; let curr = head; while(curr) { str += curr.val; strReverse = curr.val + strReverse; curr = curr.next; } return str === strReverse; } module.exports = { isPail : isPail };
