Flower Grid Arrangement

You are given an integer representing the total number of flowers. Your task is to determine whether it is possible to arrange the flowers into a grid which forms a perfect square, and each row and column contains an even number of flowers. In mathematical terms, you need to check if (n = (2k)^2 = 4k^2) for some integer (k). If this condition holds, print POSSIBLE; otherwise, print IMPOSSIBLE.

inputFormat

The first line of input contains an integer (T) representing the number of test cases. This is followed by (T) lines, each containing a single integer (n) which is the total number of flowers.

outputFormat

For each test case, output a single line with either POSSIBLE if the number of flowers can be arranged in the desired grid or IMPOSSIBLE otherwise.## sample
