A deck of poker has a total of 54 cards, from which 3 poker cards are randomly selected, if the numbers of the three poker cards are consecutive. For example: 789, A23, QKA (remarks: KA2 is not considered a straight), such three cards are called "straight", and you can replace the poker you want if you draw king and king, for example: draw king and 5 and 6 , It can be said that your own card is 567, if you randomly draw 3 poker cards from a deck of poker, how many situations are there for these 3 poker cards to be "straight".
