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) {
	char s[1001];
	int bafs,bafw,w,i,a=0;
	bafs = scanf(" %s", s);
	if (bafs == EOF) {
		return -1;
	}
	bafw = scanf(" %d", &w);
	if (bafw == EOF) {
		return -1;
	}
	for (i = 0; s[i] !='\0'; i++) {
		a++;
	}
	for (i = 0; i<a; i += w) {
		printf("%c", s[i]);
	}
	printf("\n");
	return 0;
}```
