key in the hash table, and the value in the hash table is not unique. If you sort by value only, the order of the two elements with the same value will change when other values are added or deleted. To make a stable sorting based on the hash value, you must first sort the values for the first time, and then sort the values for the second time based on the key: % Hash = (Elliot => Babbage, Charles => Babbage, Grace => Hopper, Herman => fig ); @ Sorted

Teach you how to dynamically debug your IOS app (decompile app) With this article you can learn the basics of the reverse of iOS and have a certain understanding of the security of iOS apps. Then can extrapolate, in the home App to find dangerous loopholes to prevent, to ensure user data security.In the field of security, attack and prevention exist forever.

Label:Lldb is a debugger that comes with Xcode, and as an iOS app developer, I usually use LLDB to debug code when I'm developing an app. In reverse applications, LLDB is also used to track the execution of the application. LLDB also has a Python parser built in, using Python scripts to facilitate lldb debugging, such as automating some commands, or automating the processing of data, with reference to the official documentation: LLDB Python Reference. The following is a concrete example of how

Then, make a basic example to use the functionality in this library.
