不懂......
AC代码如下
```cpp
#include<bits/stdc++.h>
using namespace std;
string a;
int main()
{
int n,ans = 0;
cin >> n;
cin >> a;
if(n == 1)
{
cout << 0;
}else
{
for(int i = 0;i < a.size() - 1;i++)
{
if(a[i] == 'V' && a[i+1] == 'K')
{
ans++;
a[i] = 'x';
a[i+1] = 'x';
}
}
for(int i = 0;i < a.size() - 1;i++)
{
if(a[i] == 'V' && a[i+1] == 'V')
{
ans++;
break;
}
else if(a[i] == 'K' && a[i+1] == 'K')
{
ans++;
break;
}
}
cout << ans;
}
return 0;
}```
