#include<bits/stdc++.h>
using namespace std;
struct aa
{
int x;
int y;
int s;
};
int dp[105][105][2];
int main()
{
int x, y, p, q;
cin >> x >> y >> p >> q;
memset(dp, 0x3f3f3f3f, sizeof(dp));
queue<aa>v;
v.push({ x,y,0 });
dp[x][y][0] = 0;
while (!v.empty())
{
auto [xx, yy, ss] = v.front();
v.pop();
for (int i = 0; i <= min(xx,p); i++)
{
for (int j = 0; j+i <= p&&j<=yy; j++)
{
if (xx - i + q < yy - j && i != xx) continue;
if (dp[x - xx + i][y - yy + j][ss ^ 1] > dp[xx][yy][ss] + 1)
{
dp[x - xx + i][y - yy + j][ss ^ 1] = dp[xx][yy][ss] + 1;
v.push({ x - xx + i,y - yy + j,ss ^ 1 });
}
}
}
}
int ans = 0x3f3f3f3f;
for (int i = 0; i <= y; i++)
{
ans = min(ans, dp[x][i][1]);
}
if (ans == 0x3f3f3f3f)
ans = -1;
cout << ans << endl;
return 0;
}
这程序好像有点Bug，我给组数据试试？
