Problem Description
Eddy's interest is very extensive, recently he is interested in prime number. Eddy discover the all number owned can be divided into the multiply of prime number, but he can't write program, so Eddy has to ask intelligent you to help him, he asks you to write a program which can do the number to divided into the multiply of prime number factor .
Input
The input will contain a number 1 < x<= 65535 per line representing the number of elements of the set.
Output
You have to print a line in the output for each entry with the answer to the previous question.
Sample Input
119412
Sample Output
112*2*13*181
分析:
简单的质因分解,从2开始依次分解。注意格式一次AC
代码:
#include<iostream>
using namespace std;
int main()
{
int n;
while (cin >> n)
{
int i;
for (i = 2; i <= n; i++)
{
while (n%i == 0)
{
n = n / i;
if (n == 1)
cout << i;
else
cout << i << '*';
}
}
cout << endl;
}
return 0;
}
