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(){
  int n, a[100], i, count = 0;
  scanf("%d", &n);
  for(i = 0; i < n; ++i) scanf("%d", &a[i]);
  for(i = 1; i < n; ++i){
    if(a[i] == a[i - 1]){
      for(int j = 1; j <= 4; ++j){
        if(a[i - 1] != j && a[i + 1] != j){
          a[i] = j;
          count++;
          break;
        }
      }
    }
  }
  printf("%d\n", count);
  return 0;
}
```
