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()
{
    long long int N,i,j,x;
    scanf("%lld",&N);
    char s[1000000],a[1000000];
    scanf("%s",s);
    a[0]=s[0];
    for(i=1,j=1; s[j]!='\0'; j++)
    {
        if(a[i-1]==s[j])
        {
            continue;
        }
        else
        {
            a[i]=s[j];
            i++;
        }
    }
    x=strlen(a);
    printf("%d",x);
    for(i=0; i<x; i++);
    {
        a[i]='\0';
    }
    return 0;
}
```
