;Task:
|
||||
Create a program to parse a single five card poker hand and rank it according to this [[wp:List_of_poker_hands|list of poker hands]].
|
||||
|
||||
|
||||
A poker hand is specified as a space separated list of five playing cards.
|
||||
|
||||
Each input card has two characters indicating face and suit.
|
||||
|
||||
|
||||
;Example:
|
||||
::::'''2d''' (two of diamonds).
|
||||
|
||||
|
||||
|
||||
Faces are: '''a''', '''2''', '''3''', '''4''', '''5''', '''6''', '''7''', '''8''', '''9''', '''10''', '''j''', '''q''', '''k'''
|
||||
|
||||
Suits are: '''h''' (hearts), '''d''' (diamonds), '''c''' (clubs), and '''s''' (spades), or
|
||||
<br>alternatively, the unicode card-suit characters: <big> ♥ ♦ ♣ ♠ </big>
|
||||
|
||||
|
||||
Duplicate cards are illegal.
|
||||
|
||||
The program should analyze a single hand and produce one of the following outputs:
|
||||
straight-flush
|
||||
four-of-a-kind
|
||||
full-house
|
||||
flush
|
||||
straight
|
||||
three-of-a-kind
|
||||
two-pair
|
||||
one-pair
|
||||
high-card
|
||||
invalid
|
||||
|
||||
|
||||
;Examples:
|
||||
2♥ 2♦ 2♣ k♣ q♦: three-of-a-kind
|
||||
2♥ 5♥ 7♦ 8♣ 9♠: high-card
|
||||
a♥ 2♦ 3♣ 4♣ 5♦: straight
|
||||
2♥ 3♥ 2♦ 3♣ 3♦: full-house
|
||||
2♥ 7♥ 2♦ 3♣ 3♦: two-pair
|
||||
2♥ 7♥ 7♦ 7♣ 7♠: four-of-a-kind
|
||||
10♥ j♥ q♥ k♥ a♥: straight-flush
|
||||
4♥ 4♠ k♠ 5♦ 10♠: one-pair
|
||||
q♣ 10♣ 7♣ 6♣ q♣: invalid
|
||||
|
||||
The programs output for the above examples should be displayed here on this page.
|
||||
|
||||
|
||||
;Extra credit:
|
||||
# use the playing card characters introduced with Unicode 6.0 (U+1F0A1 - U+1F0DE).
|
||||
# allow two jokers
|
||||
::* use the symbol '''joker'''
|
||||
::* duplicates would be allowed (for jokers only)
|
||||
::* five-of-a-kind would then be the highest hand
|
||||
|
||||
|
||||
;More extra credit examples:
|
||||
joker 2♦ 2♠ k♠ q♦: three-of-a-kind
|
||||
joker 5♥ 7♦ 8♠ 9♦: straight
|
||||
joker 2♦ 3♠ 4♠ 5♠: straight
|
||||
joker 3♥ 2♦ 3♠ 3♦: four-of-a-kind
|
||||
joker 7♥ 2♦ 3♠ 3♦: three-of-a-kind
|
||||
joker 7♥ 7♦ 7♠ 7♣: five-of-a-kind
|
||||
joker j♥ q♥ k♥ A♥: straight-flush
|
||||
joker 4♣ k♣ 5♦ 10♠: one-pair
|
||||
joker k♣ 7♣ 6♣ 4♣: flush
|
||||
joker 2♦ joker 4♠ 5♠: straight
|
||||
joker Q♦ joker A♠ 10♠: straight
|
||||
joker Q♦ joker A♦ 10♦: straight-flush
|
||||
joker 2♦ 2♠ joker q♦: four-of-a-kind
