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>

char str[101];
int main(void){
    scanf("AtCoder %s Contest", &str[0]);
    char x = str[0];
    printf("A%cC\n",x);
    return 0;
}```

Unoptimized Assembly Code:
