Python中的许多工具接受关键函数来控制元素的排序或分组方式(A number of tools in Python accept key functions to controlhow elements are ordered or grouped)。它们包括min(),max(),sorted(),list.sort(),heapq.merge(),heapq.nsmallest(),heapq.nlargest(),和itertools.groupby()。
The merge_sort function sorts the array in ascending order. The sort_ascending and sort_descending functions use merge_sort to sort the array in ascending and descending order, respectively. $ ./merge_sort.py Sorted numbers (ascending): [3, 9, 10, 27, 38, 43, 82] Sorted numbers (...
