寻找并输出11~999之间的数m,它满足m.m2和m3均为回文数. 回文:各位数字左右对称的整数. 例如:11满足上述条件 112=121,113=1331 判断一个数是否是回文数的方法:求该数的反序数,若反序数和原数相等,则为回文数,否则不是回文数. 例如:121的反序数是121,所以121是回文数 123的反序数是321,所以123不是回文数 C++代码如下: #include<iostream> using namespace std; bool symm(int m) { int i
1.打擂台 简单的小代码,打擂台.纪念下过去,祝福下新人. public static void main(String[] args){ int[] ld = {1,4,2,10,8,9,5}; int max = ld[0]; for(int i = 1;i<ld.length;i++){ if(ld[i]>max){ max=ld[i]; } } System.out.print(max); } 2.冒泡排序 还是简单的小代码,冒泡排序.纪念下过去,祝福下新人. public stati
题目描述: 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

Find the smallest prime palindrome greater than or equal to N. Recall that a number is prime if it's only divisors are 1 and itself, and it is greater than 1. For example, 2,3,5,7,11 and 13 are primes. Recall that a number is a palindrome if it read
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
