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>
int main(){
  char input[5];
  int y1,y2;
  int flag=0;
  
  scanf("%s",input);
  
  y1=(input[0]-'0')*10+(input[1]-'0');
  y2=(input[2]-'0')*10+(input[3]-'0');
  
  if(1<=y1 && y1<=12){
    flag+=2;
  }
  if(1<=y2 && y2<=12){
    flag+=1;
  } 
  
  switch(flag){
    case 0:
      printf("NA");
      break;
    case 1:
      printf("YYMM");
      break;
    case 2:
      printf("MMYY");
      break;
    case 3:
      printf("AMBIGUOUS");
  }
}```
