【示意图】这是一个从下至上的过程(Bottom-Up) 将列表不断从中间分成两个子列表,直到到达最底部,子列表中只有一个元素 然后,从下至上不断合并两个子列表,将两个子列表的所有元素排序形成一个新的列表。 【 implementation of merge sort 】 可以利用print查看每一步做了哪些操作。 【 performance analysis 】 ...
Below is a Python implementation of the Merge Sort algorithm. merge_sort.py def merge_sort(arr): if len(arr) > 1: mid = len(arr) // 2 left_half = arr[:mid] right_half = arr[mid:] merge_sort(left_half) merge_sort(right_half) i = j = k = 0 while i < len(left_half) ...
Write a Python program to sort a list of elements using the merge sort algorithm. 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 pr...

Merge Sort ImplementationTo implement the Merge Sort algorithm we need:An array with values that needs to be sorted. A function that takes an array, splits it in two, and calls itself with each half of that array so that the arrays are split again and again recursively, until a sub-...

Alex Stepanov and Meng Lee developed STL at Hewlett-Packard Laboratories, releasing the implementation in 1994.The ISO/ANSI C++ committee voted to incorporate it as a part of the C++ Standard.The STL is not an example of object-oriented programming. Instead, it represents a different programming...
