AC日记——Vicious Keyboard codeforces 801a

801A - Vicious Keyboard

 

思路:

  水题;

 

来,上代码:

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>

using namespace std;

int len,ans;

char s[205];

int check()
{
    int res=0;
    for(int i=1;i<len;i++)
    {
        if(s[i]=='V'&&s[i+1]=='K') res++;
    }
    return res;
}

int main()
{
    cin>>s+1;
    len=strlen(s+1);
    ans=check();
    for(int i=1;i<=len;i++)
    {
        if(s[i]=='V')
        {
            s[i]='K';
            ans=max(ans,check());
            s[i]='V';
        }
        else
        {
            s[i]='V';
            ans=max(ans,check());
            s[i]='K';
        }
    }
    cout<<ans;
    return 0;
}
