MBEEWALK - Bee Walk
A bee larva living in a hexagonal cell of a large honey comb decides to creep for a walk. In each “step” the larva may move into any of the six adjacent cells and after n steps, it is to end up in its original cell. Your program has to compute, for a given n, the number of different such larva walks.
The ﬁrst line contains an integer giving the number of test cases to follow. Each case consists of one line containing an integer n, where 1 ≤ n ≤ 14. SAMPLE INPUT 2 2 4
For each test case, output one line containing the number of walks. Under the assumption 1 ≤ n ≤ 14, the answer will be less than 2^31. SAMPLE OUTPUT 6 90
