Q.push(node{x,y,0,0});
while(!Q.empty()){
auto t= Q.front();
Q.pop();
auto [w,s,flag,ans] = t;
if(mark[w][s][flag]) continue;
mark[w][s][flag] = 1;
if(s == 0){
cout << ans << '\n';
return 0;
}
int cw = flag == 1 ? x - w : w;
int cs = flag == 1 ? y - s : s;
for(int i = 0; i <= min(cw,p); ++ i){
for(int j = 0; j <= cs && j + i <= p; ++j){
// if(i + j != p) continue;
if(cw - i <= cs - j + q || cs - j == 0){
Q.push(node{w + (flag == 1 ? i : -i),s + (flag == 1 ? j : -j),flag ^ 1,ans + 1});
}
}
}
}
cout << -1 ;
return 0;
}
这程序好像有点Bug，我给组数据试试？
