Problem Description
Videopoker is the slot machine variant of the currently immensely popular game of poker. It is a variant on draw poker. In this game the player gets a hand consisting of five cards randomly drawn from a standard 52-card deck. From this hand, the player may discard any number of cards (between 0 and 5, inclusive), and change them for new cards randomly drawn from the remainder of the deck. After that, the hand is evaluated and the player is rewarded according to a payout structure. A common payout structure is as follows:
Once you know the payout structure, you can determine for a given hand which cards you must change to maximize your expected reward. We'd like to know this expected reward, given a hand.
Input
On the first line one positive number: the number of testcases, at most 100. After that per testcase:
- One line with nine integers xi (0 ≤ xi ≤ 1000$) describing the payout structure. The numbers are in increasing order and describe the payout for one pair, two pair, etc, until the royal flush.
- One line with one integer n (1 ≤ n ≤ 10): the number of starting hands to follow.
- n lines, each describing a starting hand. A hand consists of five space separated tokens of the form Xs, with X being the rank (
2'...9',T',J',Q',K' orA') and s being the suit (c',d',h' or `s').
Output
Per testcase:
- One line for each starting hand with a floating point number that is the maximal expected reward for that hand. These numbers must have an absolute or relative error less than 10-6.
