@[lucy2012](/user/1252442) 第一个循环里的赋值语句打了两个等号。
就是下面这两句错了
```cpp
s[i]=='n';
s[i+1]=='n';
```

```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int n,sum=0,ns;
string s;
cin>>n>>s;
for(int i=0;i<n-1;i++){
if(s[i]=='V'&&s[i+1]=='K'){
sum++;
s[i]=='n';
s[i+1]=='n';
}
}
for(int i=0;i<n-1;i++){
if(s[i]!='n'&&s[i]==s[i+1]){
sum++;
break;
}
}
cout<<sum;
return 0;
}
```

`=`是赋值用的，`==`是判断用的

@[sqrt404](/user/637410) 所以说你又发一遍错误的代码干什么的？？

@[FreedomKing](/user/531806) 啧啧发错了

也懒得改了删了吧
