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

```c
#include <limits.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

static int calc_abs_diff (char *s) {
    char    num_str[4];
    int     num;

    /* prepare target number string */
    strncpy(num_str, s, 3);
    num_str[3] = '\0';

    num = strtol(num_str, NULL, 10);
    return abs(num - 753);
}

int main (void) {
    int     i;
    int     ans;
    int     min_diff = INT_MAX;
    int     s_len;
    char    s[11];
    scanf("%s", s);

    s_len = strlen(s);
    for ( i=0; i<s_len-2; i++ ) {
        ans = calc_abs_diff(&s[i]);
        if ( ans < min_diff )

    }
