#include <bits/stdc++.h>
using namespace std;
const int INF = 1000000;
int main(){
int x, y, p, q;
cin >> x >> y >> p >> q;
vector<vector<vector<int>>> d(2, vector<vector<int>>(x + 1, vector<int>(y + 1, INF)));
d[0][x][y] = 0;
queue<tuple<int, int, int>> Q;
Q.push(make_tuple(0, x, y));
while (!Q.empty()){

Q.pop();
if (a == 0){
for (int i = 0; i <= b; i++){
for (int j = 0; j <= c; j++){

if (d[1][b - i][c - j] == INF){
d[1][b - i][c - j] = d[0][b][c] + 1;
Q.push(make_tuple(1, b - i, c - j));
}
}
}
}
}
if (a == 1){
for (int i = 0; i <= x - b; i++){
for (int j = 0; j <= y - c; j++){
if (i + j <= p && (x - b - i + q >= y - c - j || x - b - i == 0)){
if (d[0][b + i][c + j] == INF){

}
}
}
}
}
}
int ans = INF;
for (int i = 0; i < 2; i++){
for (int j = 0; j <= y; j++){
ans = min(ans, d[i][0][j]);
}
}
if (ans == INF){
cout << -1 << endl;
} else {
cout << ans << endl;
}
}
这程序好像有点Bug，我给组数据试试？
