一、题目 Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input: 121 Output: true Example 2: Input: -121 Output: false Explanation: From left to right, it reads -121. From right to left, it becomes 121-....
Therefore it is not a palindrome.说明:从右向左读为01,因此它不是回文数Follow up: Coud you solve it without converting the integer to a string你能不能将整数换为字符串?代码class Solution { public boolean isPalindrome(int x) { if(x<0) {return false; } if(x==0) {return true; } Strin...
