#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?
