Problem
Decision trees  in particular, a type called classification trees  are data structures that are used to classify items into categories using features of those items. For example, each animal is either "cute" or not. For any given animal, we can decide whether it is cute by looking at the animal's features and using the following decision tree.
(0.2 furry (0.81 fast (0.3) (0.2) ) (0.1 fishy (0.3 freshwater (0.01) (0.01) ) (0.1) ) )
A decision tree is defined recursively. It always has a root node and a weight. It also, optionally, has a feature name and two subtrees, which are themselves decision trees.
More formally, a decision tree is defined using the following grammar.
tree ::= (weight [feature tree tree]) weight is a real number between 0 and 1, inclusive feature is a string of 1 or more lower case English lettersThe part inside the square brackets, [], is optional. The parentheses, (), weight and feature are tokens. There will be at least one whitespace character between any two tokens, except (possibly) after an openbracket '(' or before a closebracket ')'. Whitespace characters are space (' ') and endline ('\n').
To figure out how likely the animal is to be cute, we start at the root of the tree with probability p set to 1. At each node, we multiply p by the weight of the node. If the node is a leaf (has no subtrees), then we stop, and the value of p is the probability that our animal is cute. Otherwise, we look at the feature associated with the node. If our animal has this feature, we move down into the first subtree and continue recursively. If it does not have this feature, then we move down into the second subtree and continue in the same way.
For example, a beaver is an animal that has two features: furry and freshwater. We start at the root with p equal to 1. We multiply p by 0.2, the weight of the root and move into the first subtree because the beaver has the furry feature. There, we multiply p by 0.81, which makes p equal to 0.162. From there we move further down into the second subtree because the beaver does not have the fast feature. Finally, we multiply p by 0.2 and end up with 0.0324  the probability that the beaver is cute.
You will be given a decision tree and a list of animals with their features. For each item, you need to return the probability that the animal is cute.
Input
The first line of input contains a single integer, N, the number of test cases. N test cases follow.
Each test case description will start with a line that contains an integer L  the number of lines that describe a decision tree. The next L lines will contain a decision tree in the format described above. The line after that will contain A  the number of animals. The next A lines will each contain the description of one animal in the following format.
animal n feature_{1} feature_{2} ... feature_{n}
Output
For each test case, output one line containing "Case #x:" followed by exactly A lines, one per animal, in the same order as they appear in the input. Each line should contain the probability that the animal is cute. Answers that are precise to within an absolute or relative error of 10^{6} will be considered correct.
Limits

English letters.

characters, not including the endlines.
