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 <string.h>


int main(void)
{
	char s[1000001];
	scanf("%s", s);
	int i, st = strlen(s);
	int k, min = st;
	for (i = 0; i < st-1; i++){
		//printf("%d:\n", i);
		if (s[i] != s[i + 1])  {
			k = (i+1 > st -(1 + i)) ? i+1 : st-1  - i; if (k < min) min = k;
			//printf("k=%d, min=%d\n", k, min);
		}
	}
	printf("%d\n", min);
	return 0;
}```
