Problem: You have a digit sequence S of length 4. You are wondering which of the following formats S is in:    * YYMM format: the last two digits of the year and the two-digit representation of the month (example: `01` for January), concatenated in this order   * MMYY format: the two-digit representation of the month and the last two digits of the year, concatenated in this order  If S is valid in only YYMM format, print `YYMM`; if S is valid in only MMYY format, print `MMYY`; if S is valid in both formats, print `AMBIGUOUS`; if S is valid in neither format, print `NA`.
