805 - Split Array With Same Average\.
Hard
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
