2.5 归并排序(Merge sort) 归并排序:是一种分而治之的策略(divide and conquer)。采用递归算法,不断的将序列进平分成子序列,直到序列为空或只有一个元素,然后进行排序合并。其排序过程如下: python实现归并排序代码如下: View Code 归并排序的复杂度为O(n logn),但上述代码中使用了切片,会使复杂度增加。(切片...

Lisp provides various functions to find an element in a List. Each function has its own merits and demerits. In this chapter we'll explore them one by one with the help of examples.find functionfind function searches for an element, returns the first match. Returns false if element is not...
