牛客周赛 Round 29（小白）

A.小红大战小紫

#include <bits/stdc++.h>
#define IO ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
using namespace std;
    
int main()
{
    IO;
    int a, b; cin >> a >> b;

    if (a > b) cout << "kou\n";

    else if (a < b) cout << "yukari\n";

    else cout << "draw\n";
    return 0;
}

B.小红的白日梦

#include <bits/stdc++.h>
#define IO ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
using namespace std;
    
int main()
{
    IO;
    int n, ans = 0, cnt;
    string s1, s2; cin >> n >> s1 >> s2;
    
    for (int i = 0; i < n; i++) {
        cnt = 0;
        if (s1[i] == 'Y') cnt += 2;
        if (s2[i] == 'Y') cnt += 1;

        if (cnt == 1) ans += 2;
        else ans += cnt;
    }
    return cout << ans << '\n', 0;
}

C.小红的小小红

/* 
必包含xiaohong
 */
#include <bits/stdc++.h>
#define IO ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
using namespace std;
    
int mp[26] = {0};

    for(auto& x : s) mp[x - 'a']++;

    string tmp = "xiaohong";
    for (auto& x :tmp) mp[x - 'a']--;

    cout << tmp;
    for (int i = 0; i < 26; i++) {
        while (mp[i]--) {
            cout << char(i + 'a');
        }
    }
    return cout << '\n', 0;
}
