代码

//手速题#include <cstdio>#include <algorithm>#include <cstring>#define maxn 105using namespace std;int N;char s[maxn];int main(){    int i, ans=0;    scanf("%s",s+1);N=strlen(s+1);    for(i=1;i<N;i++)if(s[i]=='V' and s[i+1]=='K')ans++, s[i]=s[i+1]='.';    for(i=1;i<N;i++)if(s[i]^'.' and s[i+1]^'.' and s[i]==s[i+1]){ans++;break;}    printf("%d",ans);    return 0;}
