Cracking the coding interview 9.6
Given a matrix in which each row and each column is sorted. write a method to find an element in it. implement a function to find whether an element exists in a two-dimensional array sorted by rows and columns.
Idea: If the element to be searched is smaller than the leftmost element in a row or the rightmost element in a row, the
You are given a binary tree in which each node contains a value. design an algorithm to print all paths which sum up to that value. note that it can be any path in the tree-it does not have to start at the root.
Ideas:
Since the beginning of the path is not necessarily in the root, it is not enough to find all the paths starting from the root. Each node may start or end. If any node is used as the end node, It is pushed to the root node. If there is a sum of values in the path, it is a satisfyin

#-*-Coding: UTF-8-*-# It is more practical to use the multi-thread brute-force cracking
This article mainly introduces the python code sharing for implementing the multi-thread brute force cracking login vro function. This article provides the implementation code directly. if you need the code, refer to the "user.txt passwd.txt" file in the directory at runtime. Otherwise, an error is reported. No exception handling is added to the program. Code is frustrating .....
