Poker Flush?

Create a function that takes in two lists and determines whether there exists a flush.

• The first list represents the 5 cards dealt on the table.
• The second list represents the 2 cards in your hand.

Notation: card number and suit (abbreviated as S = Spades, H = Hearts, D = Diamonds, C = Clubs) separated by an underscore.

Examples

check_flush(["A_S", "J_H", "7_D", "8_D", "10_D"], ["J_D", "3_D"]) ➞ True // diamond flush

check_flush(["10_S", "7_S", "9_H", "4_S", "3_S"], ["K_S", "Q_S"]) ➞ True // spade flush

check_flush(["3_S", "10_H", "10_D", "10_C", "10_S"], ["3_S", "4_D"]) ➞ False

Notes

Hint: If there aren't at least 3 cards of the same suit on the table, there is zero chance of there being a flush.
