You are given n non-negative integers x1, x2, ..., xn. You are also given a positive integer E. You have to find n non-negative real numbers p1, p2, ..., pn such that p1 · x1 + p2 · x2 + p3 · x3 + .... + pn · xn = E and p1 + p2 + ... + pn = 1. If it's not possible to find n such numbers, output -1 instead. Input - The first line of the input contains a single integer T denoting the number of te
