count表示次方，如果次方=1就不用印"^"了

#include <iostream>

using namespace std;

int main(){

int n;

cin>>n;

for(int i = 2; i <= n; i ++){

int count = 0;

while(n % i == 0){

n /= i;

count++;

}

if(count >= 2){

cout<<i<<"^"<<count;

if(n !=1){

cout<<" * ";

}

}else if(count == 1){

cout<<i;

if(n !=1){

cout<<" * ";

}

}else{

}

}

return 0;

}
