首先建立最小堆,然后从后往前遍历它,由于第一个元素为最小值,把它与当前无序区的最后一个元素(i)交换,并重新调整堆使得保持最小堆结构。 defheapSort(alist):bh=BinHeap()length=len(alist)bh.build_heap(alist)foriinrange(length,0,-1):bh.items[1],bh.items[i]=bh.items[i],bh.items[1]bh....
If you are looking for the N smallest or largest items and N is small compared to the overall size of the collection, these functions provide superior performance. Thenlargest()andnsmallest()functions are most appropriate if you are trying to to find a relatively small number of items. If y...

摘要: An introduction to data structures and algorithms using the Ruby programming language. Coverage includes stacks, queues, lists, trees, recursive algorithms, elementary algorithm analysis, sorting and searching algorithms, hashing, graph representations, and depth and breadth-first search....
These are notes for Yale course CPSC 223: Data Structures and Programming Techniques for the Spring 2021 semester. Tag(s):Algorithms and Data Structures Publication date: 01 Mar 2021 ISBN-10: n/a ISBN-13: n/a Paperback: 305 pages
This free book is a concise introduction to data structures and algorithms in Ruby. Data structures are presented in a container hierarchy that includes stacks and queues as non-traversable dispensers, and lists, sets, and maps as traversable collections
