2024ICPC第一场网络赛补题

World Cup

静下心模拟很容易推，16round的时候，分成第一和第二的情况，如果第一就得赢3+3队，第二得赢2+4队，推出来6，后面double再+1就好。主要得沉下心简单推下。

#include<bits/stdc++.h>

using ll = long long;
using ull = unsigned long long;
using ari = std::array<int, 3>;
using PII = std::pair<int, int>;

const int N = 2e5 + 10;
const int mod = 1e9 + 7;
const double eps = 1e-6;

int a[N], b[N];

void solve() {

    for (int i = 1; i <= 32; i++) {
        std::cin >> a[i];
    }
    ll cnt = 0;

    for (int i = 1; i <= 32; i++) {
        if (a[i] < a[1]) cnt++;
    }

    if (cnt < 2) {
        std::cout << 32 << '\n';
    } else if (cnt < 6) {//至少6队比它菜
        std::cout << 16 << '\n';
    } else if (cnt < 13) {
        std::cout << 8 << '\n';
    } else if (cnt < 27) {
        std::cout << 4 << '\n';
    } else if (cnt < 31) {
        std::cout << 2 << '\n';
    } else std::cout << 1 << '\n';
}

signed main() {
    std::ios::sync_with_stdio(0);
    std::cin.tie(0);

    int t = 1;
    std::cin >> t;
    while (t--) {
        solve();
    }

    return 0;
}
