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

const int N=1e2+1e1+7;

map<pair<int,int>,int>vis,blk;

int n;

string s;

map<pair<int,int>,int>ans;

int dx[]={0,1,0,-1},dy[]={1,0,-1,0};

map<char,int>dir;

void dfs(int x,int y,int i)
{
    if(i==s.size())
    {
        ans[{x,y}]=1;
        return;
    }
    vis[{x,y}]++;
    int d=dir[s[i]];
    int tx=x+dx[d],ty=y+dy[d];
    if(!blk[{tx,ty}])
        dfs(tx,ty,i+1);
    if(!vis[{tx,ty}])
    {
        blk[{tx,ty}]++;
        dfs(x,y,i+1);
        blk[{tx,ty}]--;
    }
    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?
