Description

The Frobozz Magic Lock Company is in the business of manufacturing push button style combination door locks. A push button door lock consists of a number of push buttons B, (1 ≤ B ≤ 11), labeled “1” through “B”. The lock is opened by pressing the correct sequence of button combinations and then turning the doorknob. If the sequence of presses is correct, the door magically opens.

A combination consists of 1 or more buttons being pressed simultaneously. A sequence consists of a series of combinations. A sequence must have at least one combination. Once a button has been used in a combination, it may not be used again in the same sequence. In addition, it is not necessary to use all the buttons in a sequence. For example, for B = 8:

(1-2-3)(4)(7-8)

is a valid sequence with 3 combinations (1-2-3), (4), and (7-8). Note that buttons 5 and 6 are not used in this sequence.

(1-2-3)(2-4)(5-6)

is not a valid sequence, since button 2 appears in 2 combinations (1-2-3) and (2-4).

The CEO of Frobozz, J. Pierpont Flathead, wants you to write a program that determines the number of valid sequences possible for given values of B. The program must be able to process a list of lock orders (datasets) from customers and generate a report showing the order number, the value of B, and the number of valid sequences possible. This list will always contain at least one dataset, but no more than 100 datasets.

Input

The first line of input contains a single integer N, (1 ≤ N ≤ 100), representing the number of datasets that follow. Each dataset consists of a single line of data containing a single integer B, which is the number of buttons for the lock.

Output

For each dataset, display the dataset number, a blank, the value B, a blank, and the number of valid sequences.
