Question: Given an array of integers, reorder so that all the negative integers appear first, then the zeroes, and finally the positive integers. If two integers

Given an array of integers, reorder so that all the negative integers appear first, then the zeroes, and finally the positive integers. If two integers have the same sign, their order should not be changed. Use O(1) extra storage. Find an optimized solution.

I know we have to use divide and conquor, but can somehow explain how the algorithm solution works? Only psuedocode is needed, not the full program.
