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...
Python Algorithms: Mastering Basic Algorithms in the Python Language by Magnus Lie Hetland. 笔记原先是写在jupyter notebook,导出md格式后在知乎导入。全部更完之后附上ipynb文件,文章增加目录索引,食用效果更佳。 计划:(一)线性数据结构;(二)树数据机构;(三)图数据结构;(四)算法设计;(五)查找和排序;(六)...

it is faster to usemin()andmax(). Similarly, if N is about the same size as the collection itself, it is usually faster to sort it first and take a slice.

you'll also notice while Dynamic Programming problems can be the most difficult data structures and algorithms problems, they usually have a very simple and short solution to them Union Find whenever you have adisjointgraph ordisjointset, this is where Union Find is most naturally used especially...
