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

```c
#include <stdio.h>
#include <string.h>
typedef long long ll;

int len;
char str[200005];

int main()
{
    ll ans = 0;
    ll dist = 0;
        
    scanf("%s", str);
    len = strlen(str);

    for (int i = 0; i < len; i++) {
        if (str[i] == 'W') {
            ans += dist;
        }
        else {
            dist++;
        }
    }

    printf("%lld\n", ans);

    return 0;
}
