Thread: sequence

Order the cards and you should quickly see one is a sequence and one isn't

Code:

2  two of diamonds
3  three of hearts
4  four of clubs
5  five of spades
6  six of hearts

Code:

1  ace of clubs (or 14)
2  two of spades
3  three of diamonds
5  five of hearts
13 king of spades

The second is not a sequnce becaue the numbers are not contiguous.

Hopefully you've stored your cards numerically.
sort the hand lowest to highest
step through the hand
if the next card does not equal the current card plus one return 0
if you made it all the way through the hand return 1
additional logic to handle the ace

A sequence is a series of values that are all related to one another in some way. What you are looking for is called a straight -- 5 cards in sequence like
7,8,9,10,J of any suit.

In your first example, you have a 2,3,4,5,6 which is a series of 5 cards in sequence -- therefore you have a 1.

In your second example, you have a A,2,3,5,K which is not a series of 5 cards -- therefore you have a 0. The 4 is missing, and in most cases (not all) the Ace is either high or low, not high and low, making Q,K,A,2,3 not a straight. You can create your program either way you'd like though.
