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()
{
    int i;
    char s[200000]={};
    scanf("%s",&s);
    for(i=0;i<strlen(s);i++){
        if(s[i]=='?') printf("D");
        else printf("%c",s[i]);
    }    
    return 0;
}
```
