Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
//header
#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<string.h>
#include<math.h>
#include<ctype.h>
#include<stdlib.h>
#include<time.h>

//main
int main(void)
{
	char s[4];

	scanf("%s", s);

	if (strlen(s) == 2) {
		printf("%s\n", s);
	}
	if (strlen(s) == 3) {
		for (int i = 0; i<3; i++) {
			printf("%c", s[2 - i]);
		}
		printf("\n");
	}

	return 0;
}
