#include <bits/stdc++.h>
using namespace std;
const int N = 110;
int n, m, p, q;
int f[N][N];
int main() {
scanf("%d%d%d%d", &n, &m, &p, &q);
memset(f, 0x3f, sizeof(f));
f[n][m] = 0;
for (int i = n; ~i; --i) {
for (int j = m; ~j; --j) {
if (i == 0 && j == 0) continue;
for (int k = 0; k <= min(i, p); ++k) {
int _k = min(j, p - k);
for (int l = 0; l <= min(p, (m - (j - _k))); ++l) {
if ((i - k == 0) || ((i - k + q >= j - _k || i - k == 0) && ((n - i + k) + q >= (m - (j - _k)) - l || (n - i + k) == 0))) {
f[i - k][j - _k + l] = min(f[i - k][j - _k + l], f[i][j] + 1);
}
}
}
}
}
int ans = 0x3f3f3f3f;
for (int i = 0; i <= m; ++i) {
ans = min(ans, f[0][i]);
}
// cerr << f[0][100] << '\n';
// cerr << f[1][1] << '\n';
if (ans == 0x3f3f3f3f) {
// ans = -1;
puts("-1");
return 0;
}
printf("%d\n", ans * 2 - 1);
return 0;
}
这程序好像有点Bug，我给组数据试试？
