You will be given a collection of five cards (representing a player's hand in poker). If your hand contains at least one pair, return an array of two elements: true and the card number of the highest pair (trivial if there only exists a single pair). Else, return false.

Examples

highest_pair(["A", "A", "Q", "Q", "6" ]) ➞ [true, "A"]

highest_pair(["J", "6", "3", "10", "8"]) ➞ false

highest_pair(["K", "7", "3", "9", "3"]) ➞ [true, 3]

highest_pair(["K", "9", "10", "J", "Q"]) ➞ false

highest_pair(["3", "5", "5", "5", "5"]) ➞ [true, 5]

Notes

Hands with three or more of the same card still count as containing a pair (see the last example).
