Algorithms in Java

For our first excursion into the area of sorting algorithms, we shall study several elementary methods that are appropriate either for small files or for...

Before considering specific algorithms, we will find it useful to discuss general terminology and basic assumptions for sorting algorithms. We shall be considering methods of...

Although it is reasonable to learn most sorting algorithms by thinking of them as simply putting arrays of numbers into numerical order or characters into...

One of the simplest sorting algorithms works as follows: First, find the smallest element in the array, and exchange it with the element in the...

The method that people often use to sort bridge hands is to consider the cards one at a time, inserting each into its proper place...

The first sort that many people learn, because it is so simple, is bubble sort: Keep passing through the file, exchanging adjacent elements that are...

Selection sort, insertion sort, and bubble sort are all quadratic-time algorithms both in the worst and in the average case, and none requires extra memory....

Sorting algorithms are especially amenable to pictorial representations that make plain their dynamic characteristics. We have already seen, in figures throughout this chapter, several examples...

Insertion sort is slow because the only exchanges it does involve adjacent items, so items can move through the array only one place at a...

As we know from arrays and linked lists provide two of the most basic ways to structure data, and we considered an implementation of...

A number of sorting algorithms gain efficiency by taking advantage of special properties of keys. For example, consider the following problem: Sort a file of...
