Instructions: This task is to find the number of 'For' loops present in the given cpp program.
Input: int sum=0;
int main()
{
	void yinshu(int,int);//????????????????????????
	int i,n,a;
	cin>>n;
	for(i=1;i<=n;i++)
	{
		sum=0;
		cin>>a;
		yinshu(a,2);
		cout<<sum<<endl;
	}
	return 0;
}

void yinshu(int a,int x)
{
	if(a!=1)
	{
	for(int i=x;i<=a;i++)//?x?????
		if(a%i==0)//????
			yinshu(a/i,i);//?a/i??????????????i???
	}
	if(a==1)//????????????
		sum++;
}
Output:
2
