# 先看看我的
##### 然后再找找自己和我的错误
```cpp
#include<bits/stdc++.h>
using namespace std;
int a[7010],b[7010];
int main()
{
char s[110];
int n;
cin>>n;
scanf("%s",s);
int ret=0;
for(int i=0;i<n-1;i++)
{
if(s[i]=='V' && s[i+1]=='K')
{
ret++;
s[i]='*';
s[i+1]='^';
}
}
for(int i=0;i<n-1;i++)
{
if(s[i]=='V' && s[i+1]=='V')
{
ret++;
break;
}
if(s[i]=='K' && s[i+1]=='K')
{
ret++;
break;
}
}
printf("%d",ret);
return 0;
}

```
#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++;
if(temp>nowvk) nowvk=temp;
temp=0;
if(vk[i]=='K') vk[i]='V';

}
std::cout<<nowvk;
return 0;
}
```
