You are given an array of size N. Rearrange the given array in-place such that all the negative numbers occur before positive numbers.(Maintain the order of all -ve and +ve numbers as given in the original array).
Example 1:
Input:
N = 4
Arr[] = {-3, 3, -2, 2}
Output:
-3 -2 3 2
Explanation:
In the given array, negative numbers
are -3, -2 and positive numbers are 3, 2.
Your Task:
You don't need to read input or print anything. Your task is to complete the function Rearrange() which takes the array Arr[] and its size Nas inputs and returns the array after rearranging with spaces between the elements of the array.
Expected Time Complexity: O(N. Log(N)) Expected Auxiliary Space: O(Log(N))
Constraints:
1 ≤ N ≤ 107
-1018 ≤ Elements of array ≤ 1018

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
You can access the hints to get an idea about what is expected of you as well as
the final solution code.
You can view the solutions submitted by other users from the submission tab.
