Depth first search is a graph search algorithm that starts at one node and uses recursion to travel as deeply down a path of neighboring nodes as possible, before coming back up and trying other paths. const {c

这就导致可以利用 IPv6 的 scope 来绕过X-Forwarded-For: ::1%" 第二步绕过SSRF检查也有两个解法,一个是使用IPv4-mapped IPv6 address来绕过:http://[::FFFF:172.18.19.3]:8000/admin/,另一个是利用 urllib 中的 urlparse 和 requests (urllib3) 中的 urlparse 解析不一致来绕过:http://172.18.19.3:8...
你可以在下面列出的两种方法中任选其一来连接题目: 点击下面的 "打开/下载题目" 按钮通过网页终端与远程交互。如果采用这种方法,在正常情况下,你不需要手动输入 token。 在Linux、macOS、WSL 或 Git Bash 等本地终端中使用stty raw -echo; nc 202.38.93.111 10338; stty sane命令来连接题目。如果采用这种方法,你...
For each of the following, first write the algorithm, and then write the code. 1. Write a C++ blast-off program that first asks the user for a number. The program then counts backwards from the number Assume all variables are properly decl...

1) Write in pseudocode an algorithm that receives as input the root of a tree and it returns true if the tree is a proper binary tree (i.e. each internal node has 2 children) and false otherwise. Assu In C++, what is "tail rec...
Horn clause resolution experiment ABSTRACT Resolution principle is the basic theory of general logic reasoning algorithm, that is, agents can judge whether a conclusion is true or not by a series of given clause sets and combining two clauses. This principle can be used in computer efficiently, ...
