最小堆存储的序列通过树的层次遍历可以画出完全二叉树,如下图: 这里用python的list来构建最小堆,注意一开始就存在初始元素0,不去用它,但能简化后面整数除法的操作,并且最后一个元素的索引和current_size相同。 插入操作:append到items列表(保证了完全树的性质);判断新节点的值是不是比它的parent小,如果是,交换它...

In this exercise you will implement two sorting algorithms and compare their computational complexities, as measured by the number of comparisons, expressed as a function of the length of the list being sorted. Implement the following (see lecture notes for guidance): lessThan(x, y), which perf...
there is much more. The study of algorithms and data structures is central to understanding what computer science is all about. Learning computer science is not unlike learning any other type of difficult subject matter. The only way to be successful is through deliberate and incremental exposure ...

A comprehensive resource for learning and implementing algorithms and data structures. This repository includes detailed notes, complexity analysis, and code examples in C++, Java, Python, and more. Ideal for students, professionals, and those preparing
It gives programmers an easy way of adding quick notes with every Python module, function, class, and method. The strings defined using the triple-quotation mark are multiline comments. However, if such a string is placed immediately after a function or class definition or on top of a ...
