You are given an integer array `nums`.

You should move each element of `nums` into one of the two arrays `A` and `B` such that `A` and `B` are non-empty, and `average(A) == average(B)`.

Return `true` if it is possible to achieve that and `false` otherwise.

Note that for an array `arr`, `average(arr)` is the sum of all the elements of `arr` over the length of `arr`.

Example 1:

    Input: nums = [1,2,3,4,5,6,7,8]
    Output: true
    Explanation: We can split the array into [1,4,5,8] and [2,3,6,7], and both of them have an average of 4.5.

Example 2:

    Input: nums = [3,1]
    Output: false

Constraints:

- `1 <= nums.length <= 30`
- `0 <= nums[i] <= 104`
