#include<bits/stdc++.h>
using namespace std;
int a,b,c,d;
map<array<int,3>,int>p;
queue<array<int,4>>q;
int main(){
cin>>a>>b>>c>>d,q.push({0,a,b,0}),p[{0,a,b}]=0;
while(q.size()){
auto x=q.front();
q.pop();
if(x[0]==1&&x[1]==0)
cout<<x[3]<<'\n',exit(0);
if(x[0]==0){
for(int i=0;i<=x[1];i++)
for(int j=0;j<=x[2];j++)
if(i+j<=c&&(!(x[1]-i)||x[2]-j<=x[1]-i+d)&&!p.count({1,x[1]-i,x[2]-j}))
q.push({1,x[1]-i,x[2]-j,x[3]+1}),p[{1,x[1]-i,x[2]-j}]=x[3]+1;
}else{
x[1]=a-x[1],x[2]=b-x[2];
for(int i=0;i<=x[1];i++)
for(int j=0;j<=x[2];j++)
if(i+j<=c&&(!(x[1]-i)||x[2]-j<=x[1]-i+d)&&!p.count({0,a-(x[1]-i),b-(x[2]-j)}))
q.push({0,a-(x[1]-i),b-(x[2]-j),x[3]+1}),p[{0,a-(x[1]-i),b-(x[2]-j)}]=x[3]+1;
}
}
cout<<-1<<'\n';
}
这程序好像有点Bug，我给组数据试试？
