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 argc, const char * argv[]) {
    
    int n;
    char ud[3];
    int i,lf=0,rf=0,onebefore=-1;
    int count=0;
    while (1) {
        
        scanf("%d",&n);
        if (n==0) {
            break;
        }
        
        for (i = 0; i < n; i++) {
            
            scanf("%s",ud);
            
            if (0 == strcmp(ud,"ru")) {
                rf++;
                
                if (lf == rf && onebefore == 2) {
                    count++;
                }
                onebefore=0;

            } else if(0==strcmp(ud,"rd")){
                rf--;
                if (lf == rf && onebefore == 3) {
                    count++;
                }
                onebefore=1;
            } else if(0==strcmp(ud,"lu")){
                lf++;
                if (lf == rf && onebefore == 0) {
                    count++;
                }
                onebefore=2;
            } else if (0==strcmp(ud,"ld")){
                lf--;
                if (lf == rf && onebefore == 1) {

                }
                onebefore=3;
            }
            
                    }
        
        printf("%d\n",count);
        count=0;
        lf=0;
        rf=0;
        
        
    }
    return 0;
}```
