Given an array of integers arr of even length, return true if and only if it is possible to reorder it such that arr[2 * i + 1] = 2 * arr[2 * i] for every 0 <= i < len(arr) / 2. Example 1: Input: arr = [3,1,3,6] Output: false Example 2: Input: arr = [2,1,2,6] Output: false Example 3: Input: arr = [4,-2,2,-4] Output: true Explanation: We can take two groups, [-2,-4] and [2,4] to form [-2,-4,2,4] or [2,4,-2,-4]. Example 4: Input: arr = [1,2,4,16,8,4] Output: false Constraints: 0 <= arr.length <= 3 * 104 arr.length is even. -105 <= arr[i] <= 105
