```
#include <bits/stdc++.h>
int main(){
int n,nowvk=0,temp=0;
std::string vk;
std::cin>>n>>vk;
for(int i = 0 ; i < n ; i ++ ) if(i!=n-1) if(vk[i]=='V' && vk[i+1]=='K') nowvk++;
for(int i = 0 ; i < n ; i ++ ){
if(vk[i]=='V') vk[i]='K';
else vk[i]='V';
for(int j=0;j<n;j++) if(j!=n-1) if(vk[j]=='V' && vk[j+1]=='K') temp++;

else vk[i]='K';
}

return 0;
}
```
