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>
/*
void swap (char *x, char *y) {
    char temp;    // 値を一時保存する変数
    temp = *x;
    *x = *y;
    *y = temp;
}
*/

int main() {
    int n, ans = 0;
    int i, j, k;
    char c[200020] = {0};
    //int b[200020] = {0};//1なら消えている
    scanf("%d", &n);
    scanf("%s", c);
    i = -1;
    j = n ;

    do {
        do { i++; } while (c[i] == 'R');
        do { j--; } while (c[j] == 'W');
        if (i < j) {
          c[i]='R';
          c[j]='W';
            //swap(&c[i],&c[j]);
            //printf("%s\n",c);
            ans++;
        }
    } while(i<j);

    printf("%d",ans);
}
```
