#include<bits/stdc++.h>
using namespace std;
constexpr int M=105,inf=0x3f3f3f3f;
int n,m,p,q,ans=inf,dp[M][M];
int main(){
scanf("%d%d%d%d",&n,&m,&p,&q);
memset(dp,0x3f,sizeof(dp));dp[n][m]=0;
for (int i=n;~i;i--)
for (int j=m;~j;j--){
if (n!=i&&j<m+i-n-q) break;
for (int x=0;x<=p;x++)
for (int y=i?max(0,j-i-q):0,z=p-x;y<=p&&y<=j;y++)
dp[i][j]=min(dp[i][j],dp[min(n,i+z)][j-y+x]+1);
}
for (int i=0;i<=m;i++) ans=min(ans,dp[0][i]);
printf("%d\n",ans==inf?-1:ans*2-1);
return 0;
}
这程序好像有点Bug，我给组数据试试？
