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

```c
#include <math.h>
#include <stdarg.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define PI acos(-1)
typedef long long int ll;
typedef long double ld;

int main(void) {
  ll    answer;
  int   scan;
  ll    n;
  char  *s;
  answer = 0;
  scan = scanf("%lld", &n);
  s = (char *)malloc(sizeof(char) * (n + 1));
  scan = scanf("%s", s);

  ll    w;
  ll    r;
  ll    len;
  w = 0;
  r = 0;
  len = 0;
  while (s[len] != '\0') {
    if (s[len] == 'R') {
      r++;
    }
    if (s[len] == 'W') {
      w++;
    }
    len++;
  }

  ll    c;
  c = 0;
  while (c < len && r > 0) {
    if (s[c] == 'W') {
      r--;
      answer++;
    } else {
      r--;
    } 
    c++;
  }
  
  printf("%lld", answer);
  return (0);
}
```
