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>
#include<string.h>
int main()
{
	char a[100000],x;
	int i,j,t;
	scanf("%s",a);
	i=strlen(a);
	x=a[(i-1)/2];
	for(j=i/2-1;j>=0;j--)if(a[j]!=x||a[i-1-j]!=x)break;
	t=i-j-1;
	printf("%d\n",t);
	return 0;
}
```
