#include<iostream>

using namespace std;

int main(){

    int num,e=0,d=0;

    cin >> num;

int arr[100][100];

    for(int b=2,c=0;b<=num;b++){

c=0;

e=0;

for(int a=0;num%b==0;a++){

num = num/b;

c=1;

e++;

}

if(c==1&&d==1){

arr[b][e] = e;

            if(arr[b][e]!=1){

cout << " * " << b << "^" << arr[b][e];

}

else cout << " * " << b;

}

if(c==1&&d==0){

d=1;

arr[b][e] = e;

if(arr[b][e]!=1){

cout << b << "^" << arr[b][e];

}

else

            cout << b;

}

    }

return 0;

}

 

結果:WA

輸出短小

WHY??
