我感觉我的逻辑没毛病啊

using namespace std;
bool flag;
int main()
{
	int n;
	cin >> n;
	string x;
	int sn = 0;
	cin>>x;
	for (int i = 0; i < x.size();i++ )
	{
		if (n == 1)
		{
			cout << "0" << endl;
			return 0;
		}
		if (x[i] == 'V' && x[i + 1] == 'K')
		{
				sn++;
				i = i + 2;
				continue;
		}
		if (x[i]==x[i+1] && flag == false)
		{
					sn++;
					flag = true;
					i = i + 2;
					continue;
		}
		
		
	}
	cout << sn << endl;
		
	
}```
