**Problem Description**

Given an array **A** with non negative numbers, divide the array into two parts such that the average of both the parts is equal.

Return both parts (If exist). If there is no solution. return an empty list.

**NOTE:**

If multiple solutions exist, return the solution where length(A) is minimum. If there is still a tie, return the one where A is lexicographically smallest.

Array will contain only non negative numbers.

**Input Format**

First andonly argument is an integer array **A**.

**Output Format**

Return 2D array consisting of two rows where each row denoted a partition.

**Example Input**

Input 1:

A = [1 7 15 29 11 9]

Output 1:

[9 15] [1 7 11 29]

Explanation 1:

The average of part is (15+9)/2 = 12, average of second part elements is (1 + 7 + 11 + 29) / 4 = 12

NOTE:You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
