#include <bits/stdc++.h>
using namespace std;
#define int long long
#define ff first
#define ss second

struct cow{
    int a, b, c, d; // sheep, wolf, farmer position, times moved

int32_t main() {

    int x, y, p, q;
    cin >> x >> y >> p >> q;

    queue<cow> Q;
    Q.push({x, y, 0, 0});
    vis[x][y][0] = true;

    int ans = INT64_MAX;
    while(!Q.empty()) {
        cow f = Q.front();
        Q.pop();

        if (f.a == x && f.c == 1) { 
            ans = min(ans, f.d);
        }

        for (int i = 0; i <= min(p, f.a); i++) {
            for (int j = 0; j <= min(p - i, f.b); j++) {
                int state1 = f.a - i;
                int state2 = f.b - j;
                int state3 = x - state1;
                int state4 = y - state2;

                if ((state1 + q < state2 && state1 > 0 ) || vis[state3][state4][f.c ^ 1]) {
                    continue;
                }


                vis[state3][state4][f.c ^ 1] = 1;
                Q.push({state3, state4, f.c ^ 1, f.d + 1});
            }
        }
    }

    if (ans == INT64_MAX) {
        cout << -1 << '\n';
    } else {
        cout << ans << '\n';
    }

    return 0;
}

这程序好像有点Bug,我给组数据试试?
