This task is to find the number of 'For' loops present in the given cpp program.
Q: int su(int input)//?????????
{
int ju=1;
for(int i=2;i<sqrt(input);i++)
{
if(input%i==0) ju=0;
break;
}
return ju;
}
int fenjie(int input, int k)//k???????????input??????
{
int ret=1;//re??????????????
for(int i=k;i<=sqrt(input);i++)
{
if(input%i==0)
{
if(su(input/i)==0);//????????????????????
{
ret=fenjie(input/i,i)+ret;
}
}
}
return ret;
}
int main()
{
int input,num,sol;
cin>>num;
while(num--)//????
{
cin>>input;
cout<<fenjie(input,2)<<endl;//sol??????????
}
return 0;
}
