#include<bits/stdc++.h>
using namespace std;
int x,y,p,q;
bool comp(int a,int b){
return (0 <= a and a <= x and 0 <= b and b <= y);
}
int main(){
cin >> x >> y >> p >> q;
bool dp[x+100][y+100][3];
memset(dp,0,sizeof(dp));
int ans = -1;
queue<array<int,4>> bfs;
bfs.push({x,y,-1,0});
dp[x][y][0] = true;
while(!bfs.empty()){
array<int,4> curr = bfs.front();
bfs.pop();
if(curr[0] == 0){
ans = curr[3];
break;
}
for(int i = 0;i <= x;i++){
for(int j = 0;j <= y;j++){
if(i+j > p){
continue;
}
array<int,4> next = curr;
next[0] += i*curr[2];
next[1] += j*curr[2];
next[2] *= -1;
next[3]++;
if(!comp(next[0],next[1])){
continue;
}
if(curr[2] == -1 and next[1] > next[0]+q and next[0] != 0){
continue;
}
if(curr[2]==1 and y-next[1] > (x-next[0])+q and (x-next[0]) != 0){
continue;
}
if(dp[next[0]][next[1]][next[2]+1]){
continue;
}
dp[next[0]][next[1]][next[2]+1] = true;
bfs.push(next);
}
}
}
cout << ans << endl;
}
这程序好像有点Bug，我给组数据试试？
