本人思路有些不寻常

#include<bits/stdc++.h>
using namespace std;
int n,cc,l,aa;
string a;
int main(){
	cin>>n;
	cin>>a;
	for(int i=0;i<n;i++){
		l++;
		if(a[i]=='V'&&a[i+1]=='K'){
			cc++;
		}
		if(a[i]=='V'&&a[l]=='K'){
			aa++;
		}
		if(a[l]=='V'&&a[i+1]=='K'){
			aa++;
		}
	}
	if(aa>=1){
		cc++;
	}
	cout<<cc;
	return 0;
}
