1.2 算法的心脏:详解merge操作 (The Heart of the Algorithm: A Detailed Explanation of themergeOperation) 如果说归并排序是一部精密的机器,那么merge函数就是驱动这部机器运转的引擎。理解了merge,就理解了归并排序的半壁江山。 merge操作的目标非常明确:输入两个已经排好序的数组(或
Note: According to Wikipedia "Merge sort (also commonly spelled mergesort) is an O (n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output." Algorithm: Conceptual...
Abstract base classes provide a blueprint for concrete classes. They don't contain implementation. Instead, they provide an interface and make sure that derived concrete classes are properly implemented. Abstract base classes cannot be instantiated. Mutable default parameter If python function default in...
The decimal module offers a Decimal datatype for decimal floating point arithmetic. Compared to the built-in float implementation of binary floating point, the class is especially helpful forfinancial applications and other uses which require exact decimal representation, control over precision, control...

Python has its own implementation of sort() function, and another is sorted() function where sort() will sort list whereas, the sorted function will return new sorted list from an iterable. The list.sort() function can be used to sort the list in ascending and descending order and takes ...
