A reversible prime in any number system is a prime whose "reverse" in that number system is also a prime. For example in the decimal system 73 is a reversible prime because its reverse 37 is also a pr

返回目录题意给出整数n和radix，如果n是素数，且n在radix进制下反转后的数在十进制下也是素数，则输出“Yes"; 否则输出“No”。样例（可复制）73 1023 223 10-2//outputYesYesNo注意点注意n=1的情况#include<bits/stdc++.h>using namespace std;bool isprim...

一个数N(为十进制)，判断他是否为质数
将N转换为D进制 翻转看其十进制的值是否为质数
如果都为质数Yes，否则No
例如：7 3 （7本身为质数；三进制表示21，那么翻转12，12的十进制值4，不是质数；综上结果No）
此题sqrt 求平方根函数，在头文件#include<math.h>

我丢，又读假题了。。。理解成十进制系统下的质数判断了 看到系统，不免想起被离散支配的恐惧+_+ 题意 给定两个整数 \(N\) 和 \(D\)，如果 \(N\) 是一个质数，并且将 \(N\) 转化为 \(D\) 进制表示后，再进行反转，得到的新数字转化为十进制表示后如果也是一个质数，则称 \(N\
