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

```c
// abc053d: Card Eater
#include <stdio.h>

#define upto(i,s,e,d) for(int i=(s);i<=(e);i+=(d))
#define in(n) scanf("%d",n)
#define out(d) printf("%d\n",d)

#define MAX 100000
int b[MAX+1];

int main(){
  int n;in(&n);
  int c=0;
  upto(i,0,n-1,1){
    int a;in(&a);
    if(b[a]==0){
      b[a] = 1;
      c++;
    }
  }
  out(c%2? c: c-1);
  return 0;
}```
