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 <string.h>
int main(){
	char str[30];
	if(fgets(str, 30, stdin) == NULL){
		printf("error\n");
		exit(1);
	}

	int len = strlen(str);
	int count = 0;
	char* ans = "yes";
	for(int i=0;i<len;i++){
		for(int j=0;j<i;j++){
			if(str[i] == str[j]) ans = "no";
		}
	}

	printf("%s\n", ans);
	return 0;
}```
