# Challenge: Re-arrange Positive & Negative Values

Given an array, can you re-arrange its elements in such a way that the negative elements appear at one side and positive elements appear at the other? Solve this problem in Java and see if your code runs correctly!

We'll cover the following

## Problem Statement #

In this problem, you have to implement the void reArrange(int[] arr) method, which will sort the elements, such that all the negative elements appear at the left and positive elements appear at the right.

Note: Consider 0 as a positive number.

#### Method Prototype #

void reArrange(int[] arr)


#### Output #

A sorted array with negative elements at the left and positive elements at the right.

#### Sample Input #

arr = {10, -1, 20, 4, 5, -9, -6}


#### Sample Output #

arr = {-1, -9, -6, 10, 20, 4, 5}


Note: Order of the numbers doesnâ€™t matter.

{-1, -9, -6, 10, 20, 4, 5} = {-9, -1, -6, 10, 4, 20, 5}
