0805. Split Array With Same Average

https://leetcode.com/problems/split-array-with-same-average

Description

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
