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>
#include<string.h>	
#include<math.h>
char s[200005];
void swap(char *a,char *b){
	char c=*a;
	*a=*b;
	*b=c;
}
int main(){
	int n,ans=0;
	scanf("%d",&n);
	scanf("%s",s);
	int left=0,right=n-1;
	while(left<right){
		if(s[left]=='W'&&s[right]=='R'){
			swap(&s[left],&s[right]);
			left++;
			right--;	
			ans++;
		}
		else if(s[left]!='W')left++;
		else if(s[right]!='R')right--;
	} 
	printf("%d",ans);
	return 0;
} ```
