    This is a quickSelect algorithm to find the k-th smallest element in an unsorted array of numbers. It is in place and non-recursive to save memory (meaning its extra memory is O(1)). Further, if the list is randomly sorted, it should ignore half the list each time it parses through it which results in an O(n) complexity. Here is a quick example … Building a Next Index Array.
