Statement

 Goal

In this simplified version of "Card Counting", you are playing Blackjack at a casino table that uses only one standard deck of 52 cards.

Fortunately, you have an amazing memory and incredible math skills.
Unfortunately, you are easily distracted and there's a lot going on.

Your streamOfConsciousness is what you observe intermingled with your thoughts.
Each thought or observation (separated by a period .) might be a series of cards or something else. It is a series of cards if it consists solely of valid cards; see abbreviations used below.

With your knowledge of all the observed cards, calculate the percentageChance (rounded to the nearest whole number) that the value of the next card will be less than the bustThreshold.
(The bustThreshold is what would make your hand "go-bust"/lose by going over 21. It isn't anything you need to calculate; it is provided.)

Abbreviations used, and values:
K = King
Q = Queen
J = Jack
T = Ten
(each of the above has a value of 10)
A = Ace (has a value of 1)
• Each number card (2 through 9, inclusive) has its own face value

Examples:
JT7A44 means: a Jack, a Ten, a 7, an Ace, and two 4s
JAKE might be your buddy, but it's not a series of cards, since "E" isn't a valid abbreviation
AT&T might be your cell-service provider, but it's not a series of cards, since "&" isn't a valid abbreviation
T1 might be a data/telecom line, but it's not a series of cards, since "1" isn't a valid abbreviation
Input
Line 1: a string streamOfConsciousness
Line 2: an integer bustThreshold
Output
Line 1: an integer percentageChance%
