Quick Sort Exercise 4. Suppose the signature of a Quick Sort routine is: public void quickSort(int a[ ], int start, int end) If a.length yields a value of 32, what should be the values passed by Sand g when the routine is initially called via: quickSort(a, f, g); 5. Into how many partitions is the array divided upon each recursion? 6. Explain how the pivot value is used to separate the list into two halves. 7. How is the pivot value usually calculated? 8. Pick out the line or lines of code that demonstrate that Quick Sort is recursive. 9. Assume that is the pivot value and that we are operating under the rules: While afi) pivot value, increment i While alij > pivot value, decrement Interchange ali) and all as long as i 4791623 58 j What two values will get interchanged first
