用字符串对比不就行了

 *   this.val = x;
 *   this.next = null;
 * }
 */

/**
 * 
 * @param head ListNode类 the head
 * @return bool布尔型
 */

    // 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;
