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

```c
#include <stdio.h>
#include <stdlib.h>

int main()
{
	long long N;
	scanf("%lld", &N);
	
	int n, sum = 0, ans;
	for (n = 1; N >= 10; n++, N /= 10) sum += N % 10;
	
	if (n == 1) ans = N;
	else if (sum == (n - 1) * 9) ans = sum + N;
	else ans = (n - 1) * 9 + N - 1;
	
	printf("%d\n", ans);
	fflush(stdout);
	return 0;
}```
