个人思路：
大鱼要想吃到小鱼，必须：
- 方向相反
- 大鱼之前没有被更大的鱼吃掉
于是就有了我下面的蒟蒻代码：
```cpp
#include<cstdio>
#include<cstring>
int main(){
FILE *fin,*fout;
fin=fopen("fish.in","rb");
fout=fopen("fish.out","wb");
int n,a[2010][2],b[2010];
memset(b,0,sizeof(b));
fscanf(fin,"%d",&n);
for(register int i=1;i<=n;i++){
char c;
fscanf(fin,"%d %c",&a[i][0],&c);
if(c=='L')a[i][1]=-1;else a[i][1]=1;
}
for(register int i=1;i<=n;i++){
if(b[i])continue;
for(register int j=i+a[i][1];j<=n&&j>0;j+=a[i][1]){
if(b[j])continue;
if(a[i][0]<a[j][0]&&a[i][1]+a[j][1]==0){b[i]=1;break;}
if(a[i][0]>a[j][0]&&a[i][1]+a[j][1]==0)b[j]=1;
}
}
int ans=0;
for(register int i=1;i<=n;i++)if(!b[i])ans++;
fprintf(fout,"%d",ans);
fclose(fin);fclose(fout);
return 0;
}
```

dalao话说这好像是2016安庆市赛的题目（虽然我是不是安庆人）……亲测小学组能过，初中组就不一定了。
