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 <stdlib.h>
#include <math.h>
#include <stdbool.h>

#define lli long long int
#define min(a,b) ((a)<(b)?(a):(b))
#define max(a,b) ((a)>(b)?(a):(b))
#define	abs(a) ((a)<0?-(a):(a))



int main(void){
	char *s;
	int i;
	s = calloc(sizeof(char),13);
	scanf("%s",s);
	for(i=0;i<4;i++){
		printf("%c", s[i]);
	}
	printf(" ");
	for(i=4;i<12;i++){
		printf("%c", s[i]);
	}
	printf("\n");
	return 0;
}```
