Codeforces Round #633 (Div. 2) A. Filling Diamonds
You have integer nn. Calculate how many ways are there to fully cover belt-like area of 4n−24n−2 triangles with diamond shapes.
Diamond shape consists of two triangles. You can move, rotate or flip the shape, but you cannot scale it.
22 coverings are different if some 22 triangles are covered by the same diamond shape in one of them and by different diamond shapes in the other one.
Please look at pictures below for better understanding.

These are the figures of the area you want to fill for n=1,2,3,4n=1,2,3,4.
You have to answer tt independent test cases.
The first line contains a single integer tt (1≤t≤1041≤t≤104) — the number of test cases.
Each of the next tt lines contains a single integer nn (1≤n≤1091≤n≤109).
For each test case, print the number of ways to fully cover belt-like area of 4n−24n−2 triangles using diamond shape. It can be shown that under given constraints this number of ways doesn't exceed 10181018.
