```cpp
#include <bits/stdc++.h>
using namespace std;
stack<int> st;
int x,n,ans,sizen;
inline int read(){

char ch=getchar();

}
while (ch>='0'&&ch<='9'){

}
return x*f;
}
inline void write (int x) {
if (x < 0) {
putchar ('-');
x = -x;
}
if (x > 9)
write (x / 10);
putchar (x % 10 + '0');
}
int main(){
n=read();
while(n--){
x=read();
int t=1;
while (sizen && x>=st.top()){
if (st.top()==x)

ans++;
}
while (t--){

}
```
现在加入了快写,仍然是3个 $TLE$ ,希望大家的帮助。
