他說我在輸入261855的時候，答案會是：2 * 3^2 * 5 * 11 * 23^2 ，但我自己測試是正確的(3^2 * 5 * 11 * 23^2)

#include <iostream>

using namespace std;

int main()
{
int n=0;
int counter=0;
while(cin >> n)
{
for(int i=2;i<=n;i++)
{
while(n%i==0)
{
n=n/i;
counter++;
}
if(counter>1)
{
if(n!=1)
{
cout << i << "^" << counter << " " << "*" << " " ;
counter=0;
}
else
{
cout << i << "^" << counter << endl ;
break;
}
}
else if(counter==1)
{
if(n!=1)
{
cout << i << " " << "*" << " " ;
counter=0;
}
else
{
cout << i << endl ;
break;
}
}
}
}
return 0;
}

我是這樣寫

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
        int a,b,c;
      
     
        
    while(cin>>a)
    {
    	b=2;

        while(b<=a)
        {
                c=0;
                while(a%b==0)
                {
                        a=a/b;
                        c=c+1;       
                }
                if(c>0)
                {
                        cout<<b;
                        if ( c > 1 ) cout << "^" << c ;
                        if ( a > 1 ) cout << " * " ;
                }
                b++;  
        } 
        cout<<endl;
   }
}
