#include <bits/stdc++.h>
using namespace std;
const int inf = 1e9;

int main() {
	int x, y, p, q;
	cin >> x >> y >> p >> q;

	vector<vector<vector<int>>>	dp(2, vector<vector<int>>(110, vector<int>(110, inf)));

	dp[0][x][y] = 0;

	queue<array<int, 3>> Q;
	Q.push({0, x, y});

	while (!Q.empty()) {
		auto [pos, a, b] = Q.front();
		Q.pop();

		if (pos == 1 && !a) {
			cout << dp[1][0][b];
			return 0;
		}
		for (int i = 0; i <= (!pos ? a : x - a); i++)
			for (int j = 0; j <= (!pos ? b : y - b); j++) {
				if (i + j > p)
					break;
				if (!pos && a - i + q < b - j && a - i > 0)
					continue;
				if (pos && x - a - i + q < y - b - j && x - a - i > 0)
					continue;
				int na, nb;
				if (!pos)
					na = a - i, nb = b - j;
				else
					na = a + i, nb = b + j;
				if (dp[pos ^ 1][na][nb] > dp[pos][a][b] + 1) {
					dp[pos ^ 1][na][nb] = dp[pos][a][b] + 1;
					Q.push({pos ^ 1, na, nb});
				}
			}
	}

	cout << -1;
}

这程序好像有点Bug,我给组数据试试?
