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[12];
char t[13];
int i;
scanf("%s",s);
for(i=0;i<13;i++){
if(i<4) t[i]=s[i];
else if (i==4) t[i]=' ';
else t[i]=s[i-1];
}
for(i=0;i<13;i++){
printf("%c",t[i]);
}
printf("\n");
return 0;
}```
