桐桐数：一个数若能分解为两个素数的乘积，那么这个数就是桐桐数。~~虽然我也不知道桐桐是谁但是洛谷上也有桐桐的题~~

#include <iostream>
#include <cmath>
using namespace std;
bool prime(int n)
{
	int prime = 1;
	for (int i = 2; i <= sqrt(n); i++)
	{

			break;
		}
	}
	if (prime == 1)
	{
		return true;
	}
	else
	{
		return false;
	}
}

后面基本上是二维数组的专项练习（虽然我也有用一维数组），大致的思路其实都是类似的，哪怕难一点稍微花一点时间也是可以想出来的，所以就不写注释了。
