MergeX (Algorithms 4/e)

Object
- edu.princeton.cs.algs4.MergeX

```
public class MergeX
extends Object
```
The MergeX class provides static methods for sorting an array using an optimized version of mergesort.
In the worst case, this implementation takes Θ(n log n) time to sort an array of length n (assuming comparisons take constant time).
This sorting algorithm is stable. It uses Θ(n) extra memory (not including the input array).
For additional documentation, see Section 2.2 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static void`	`main(String[] args)` Reads in a sequence of strings from standard input; mergesorts them (using an optimized version of mergesort); and prints them to standard output in ascending order.
`static void`	`sort(Comparable[] a)` Rearranges the array in ascending order, using the natural order.
`static void`	`sort(Object[] a, Comparator comparator)` Rearranges the array in ascending order, using the provided order.

```
public static void sort(Comparable[] a)
```
    Rearranges the array in ascending order, using the natural order.
    
    Parameters:
    
    a - the array to be sorted
  - sort
```
public static void sort(Object[] a,
                        Comparator comparator)
```
    Rearranges the array in ascending order, using the provided order.
    
    Parameters:
    
    a - the array to be sorted
    
    comparator - the comparator that defines the total order
  - main
```
public static void main(String[] args)
```
    Reads in a sequence of strings from standard input; mergesorts them (using an optimized version of mergesort); and prints them to standard output in ascending order.
