Asked in companies
You are given an array 'ARR' consisting of 'N' integers. You need to rearrange the array elements such that all negative numbers appear before all positive numbers.
Note:
The order of elements in the resulting array is not important.
Example:
Let the array be [1, 2, -3, 4, -4, -5]. On rearranging the array such that all negative numbers appear before all positive numbers we get the resulting array [-3, -5, -4, 2, 4, 1].
