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>
int main(void)
{
    char s[100001],t[50001];
    int i=0,j=0;
    
    scanf("%s",s);
    while((s[i]>='a')&&(s[i]<='z')){
        t[j]=s[i];
        i=i+2; j++;
    }
    printf ("%s\n",t);
    return 0;
}```
