你需要找到由两个 n 位数的乘积组成的最大回文数.由于结果会很大,你只需返回最大回文数 mod 1337得到的结果.示例:输入: 2输出: 987解释: 99 x 91 = 9009, 9009 % 1337 = 987说明:n 的取值范围为 [1,8].详见:https://leetcode.com/problems/largest-palindrome-product/description/ C++: class Solution { public: int largestPalindro…

Find the largest palindrome made from the product of two n-digit numbers. Since the result could be very large, you should return the largest palindrome mod 1337. Example: Input: 2 Output: 987 Explanation: 99 x 91 = 9009, 9009 % 1337 = 987 Note: The…

479. 最大回文数乘积 你需要找到由两个 n 位数的乘积组成的最大回文数. 由于结果会很大,你只需返回最大回文数 mod 1337得到的结果. 示例: 输入: 2 输出: 987 解释: 99 x 91 = 9009, 9009 % 1337 = 987 说明: n 的取值范围为 [1,8]. PS: 举个例子: max = 99; 从i= 98开始循环 构造出回文数 rev = 9889 对于 x = 99 ,rev不能整除,继续 对于 x = 98 , 98 * 98 = 9604,小于r…
