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>

int main(void){
	int i=0,j;
	char A[1200];
	gets(A);
	while(A[i]!='\0'){
		i++;
	}
	for(j=0;j<=i;j++){
		if('A'<=A[j] && A[j]<='Z') A[j]=A[j]+32;
		else if('a'<=A[j] && A[j]<='z') A[j]=A[j]-32;
	}
	printf("%s\n",A);
	return 0;
}```
