When my quicksort is passed a large array of words, i get a stackOverflow error, what can i do so it doesnt end up in an infinite recursive loop
Homework Answers
If quickSort() is still using pivot x = a[p], and not x = a[(p+r)/2], then if the data is already sorted, quickSort() will probably get stack overflow (this will also happen if there are a lot of duplicates). Any chance that you're running quickSort() on data that's already been sorted by a prior sort?

HW60.1. Array Quicksort You've done partition so now it's time to finish Quicksort. Create a public non-final class named Quicksort that extends Partitioner. Implement a public static method void quicksort (int] values) that sorts the input array of ints in ascending order. You will want this method to be recursive, with the base case being an array with zero or one value. You should sort the array in place, which is why your function is declared to return void. If...

quickSort function. Calling previous functions already implemented. This is a bit different type of quicksort function where my partition function has 3 parameters instead of 4. So I need to write a function quicksort that actually puts all 3 of my functions together and finalizes the sorting process "There should be almost nothing done besides calling the other 3 functions and recursively calling itself (except to check for basecase) class quicksort { private: int left; int right; int* array; ...

This assignment simply requests that you take the quicksort algorithm that you have been working with and make it generic. You are to demonstrate the effectiveness of your work by defining the main method that passes a list of Integers, Doubles, and Strings and sorts them all.
