使用Python实现直接插入排序.希尔排序.简单选择排序.冒泡排序.快速排序.归并排序.基数排序. #! /usr/bin/env python # DataStructure Sort # InsertSort def InsertSort(lst, end=None, beg=0, space=1): if end is None: end = len(lst) for i in range(beg, end, space): tmp = lst[i] j = i-space while j…

用Python模拟栈和队列主要是利用List,当然也可以使用collection的deque.以下内容为栈: #! /usr/bin/env python # DataStructure Stack class Stack: def __init__(self, data=None): if data is not None: self.stk = [data] self.top = 0 else: self.stk = [] self.top = -1 def __str__(self): r…

最近一直在学习Python和Perl这两门语言,两者共同点很多,也有不多.希望通过这样的模拟练习可以让自己更熟悉语言,虽然很多时候觉得这样用Python或者Perl并没有体现这两者的真正价值. #! /usr/bin/env python # DataStructure Linkedlist class Node: """ Member Variable: 1. next 2. data """ def __init__(self, data):…

The HTML specifications technically define the difference between "GET" and "POST" so that former means that form data is to be encoded (by a browser) into a URL while the latter means that the form data is to appear within a message b…

The unstable gradient problem: The fundamental problem here isn't so much the vanishing gradient problem or the exploding gradient problem. It's that the gradient in early layers is the product of terms from all the later layers. When there are many…
