#include<bits/stdc++.h>
using namespace std;

int d=dir[s[i]];
int tx=x+dx[d],ty=y+dy[d];

dfs(tx,ty,i+1);

}
vis[{x,y}]--;
}
int main()
{
dir['L']=3;
dir['R']=1;
dir['U']=0;
dir['D']=2;
cin>>n;
cin>>s;
dfs(0,0,0);
printf("%d\n",(int)ans.size());
for(auto [p,e]:ans)
printf("%d %d\n",p.first,p.second);
}
这程序好像有点Bug，我给组数据试试？
