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 s[100001],ck;
    int len,i,count;
    while(gets(s)!='\0')
    {
        count=0;
        len=strlen(s);
        ck=s[len-1];
        for(i=len-2;i>=0;i--)
        {
            if(ck!=s[i])
               {
                   ck=s[i];
                   count++;
               }
        }
        printf("%d\n",count);
    }
    return 0;
}
