Sequence

Hi, please can someone help me with this.

I want to write a function sequence that returns 1 when a set of 5 cards appear in sequence ; 0 is not.

I dont understand very well what to do here.

the sequence is 2,3,4,5,6,7,8,9,10,jack,queen,king, with ace considered as either before 2 or after king as needed

For example the set of cards( given as follow):

two of diamonds
four of clubs
six of hearts
three of hearts
five of spades

must have sequence =1;

but for the set of cards:

two of spades
king of spades
ace of clubs
three of diamonds
five of hearts

must have sequnce =0
I give this second example since I do not understand why the sequence is 0 here.

Can someone explain me what sequence means and give me some suggestions to write the function called sequence??
Please do not use structure

Thank you for your time.

To me example one looks doubtful becuase card 4th is not in sequence.

By sequence I guess the card should appear as ordered in terms of its face value.

that is in the first example, first 3 cards are in sequence in the sence that it has increasing face value.

If you see secnd example carefully, the cards are forming a ring sequence since 2 < King < Ace < three , Five

i.e till king value is increasing and then decreasing ( Ace ) and then increasing.

Since "Ace" is the only card that act as a ring card.

Thank you,
this means that I need to make a special case where ACE is at the beginning and ACE at the end in my function, right?

Yes . Ace is the special card.
