Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include <stdio.h>
#define max(a, b) ((a)<(b) ? (b) : (a))
int main(){
  long long int x = 0, ans = 0;
  int n;  scanf("%d", &n);
  char s[102];  scanf("%s", s);

  for(int i=0; i<n; i++){
    if(s[i] == 'D'){
      x--;
    }else{
      x++;
      ans = max(ans, x);
    }
  }
  printf("%lld\n", ans);
  return 0;
}
```
