Can you solve this real interview question? Find the Closest Palindrome - Given a string n representing an integer, return the closest integer (not including itself), which is a palindrome. If there is a tie, return the smaller one. The closest is defin
接下来考虑到数量级的进位退位,对于一个四位数的n来说,与其最接近的三位数长度的回文数是999,最接近的五位数长度是10001。所以最后在这五个数字中得出符合题目要求的答案。 代码如下: classSolution(object):defnearestPalindromic(self, n):""":type n: str :rtype: str"""l=list(n) low=0 high= len(l...
leetcode 564. Find the Closest Palindrome leetcode564题目地址 Given an integer n, find the closest integer (not including itself), which is a palindrome. The 'closest' is defined as absolute difference minimized between two integers. Example 1: Input: "123" Output: "121" Note: The input n...

给定一个正整数字符串,长度不超过18,求离他最近的回文数字,如果存在两个距离一样近,取值小的那个。 令,不可以取这个数本身。 字符串取值范围 [1,1018−1] example Input: n = "123" Output: "121" 思路 贪心,由于要取最近的数字,要使数字变化尽量小。所以,我们尽量保留前半部分。 我们将数抽象成 ...
