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>

int main() {
    int n, l = 0;
    char c, d;
    scanf("%d", &n);
    c = getchar();
    c = getchar();
    while(n > 1) {
        d = getchar();
        n--;
        if(c != d) {
            l++;
            n--;
            c = getchar();
        } else {
            c = d;
        }
    }
    printf("%d\n", l);
    return 0;
}
