Answer the given question with a proper explanation and step-by-step solution.
In Java, please.
Consider the following problem.
Input: an array of integers A[]
Output: rearranges the array to have the following property:
Suppose the first element in the original array A[], A[0] = x.
In the rearranged array, suppose that x is at index i, that is A[i] = x. Then, we want the rearranged array to be such that A[j] <= x for all j < i and A[j] > x for all j > i. The rearranging should place all the values less than (or equal to) x to the "left" of x and all values larger than x to the right of x.
Here's an example. Suppose the array has the elements in this initial order:
4 3 9 2 7 6 5
A[0] = 4.
After rearranging elements, we get:
3 2 4 5 9 7 6
That is, A[0] = 4, is positioned in the resulting array so that all elements less than 4 (that is, 2, 3) are to its left (in no particular order), and all elements larger than 4 are to its right (again, in no particular order).
