Often times when we have a collection of values, we are more interested in the order statistics of the collection: find the min value, find the max value, find the K'th smallest value, and what have you. There are a number of data structu
Heaps are ubiquitous in computer science. If you need the minimum, or maximum of a collection, few choices are better than a heap for getting them. Heap-forming algorithms are the foundation of many different algorithms and data structures. From heapso
For the first 15 years or so of computing if you wanted an in-place general purpose sorting algorithm you were stuck with O(n^2) sorting algorithms. Insertion sort, selection sort, and bubble sort were about as far as
Searching and sorting are the two most common processes performed on a computer, and for that reason a lot of research has gone into the various methods of performing those tasks. Range searching is an expansion of general sear
