#include<bits/stdc++.h>
using namespace std;
using ll=long long;
int T,n;
char dir[5]="NWSE";
int trans(char c){
	return find(dir,dir+4,c)-dir;
}
void work(){
	scanf("%d",&n);
	int cur=-1;
	vector<pair<char,int>>ans;
	char st;
	for(;n--;){
		char str[9];
		int x;
		scanf("%s%d",str,&x);
		int p=trans(*str);
		if(cur==-1){
			st=dir[p];
			cur=p;
		}else{
			if(cur!=p){
				if(p==(cur+1)%4)ans.push_back({'L',0}),(cur+=1)%=4;
				else ans.push_back({'R',0}),(cur+=3)%=4;
			}
		}
		ans.push_back({'Z',x});
	}
	printf("%ld %c\n",ans.size(),st);
	for(auto [x,y]:ans){
		if(x=='Z')printf("%c %d\n",x,y);
		else printf("%c\n",x);
	}
}
int main(){
	for(scanf("%d",&T);T--;)work();
	return 0;
}

这程序好像有点Bug,我给组数据试试?
