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

```c
i,s;main(k){
  
    scanf("%d",&k);
    for(i++;i<=k;i++){
        s=(s*10+7)%k;
        
        if(s%k==0){
            printf("%d",i);
            return 0;
        }
    }
    printf("-1");
}
```
