Express As The Sum#8676
Given an integer , express it as the sum of at least two consecutive positive integers. For example:
10 = 1 + 2 + 3 + 4
24 = 7 + 8 + 9
If there are multiple solutions, output the one with the smallest possible number of summands.
The first line contains the number of test cases (1 \le t \le 50). The descriptions of the test cases follow:
Each test case consists of one line containing an integer (1 \le n \le 10^9).
For each test case, output a single line containing the equation in the format:
n = a + (a + 1) + ... + b
as in the example. If there is no solution, output a single word "IMPOSSIBLE" instead.
