Implementation principle:
Quick sort: The key is to take any value out of the queue, place it in the correct position (the left is less than or equal to this number, the right is greater than or equal to this number), and make sure that each number of its own position is sorted from small to large.
Merge sort: First the queue is unpacked into two smaller queues, the small queues are sorted sequentially, then the small queues are merged and the order is ensured.

Learning C + + is annoying, because you need to know a lot of details, I can not know so many details, but I want to use this language to do something.
Simply put, C + + is an object-oriented language, but compared to other object-oriented language Java C #, it is closer to the bottom.
C + + is very special, like a big grocery store, everything, but the tools are too simple, ordinary people hold not live.

to call it in Chinese, what's the word array?Speaking of arrays, we have to say array literals, arrays are actually special objects, objects have unique properties and methods, through the object name. Property, Object. Method () to take values and calls, while arrays are evaluated by subscript, array literals is similar to array, is a collection of data types, but array literals is essentially an object, declaration, and invocation, which is different from an array.

Typically, we set the password to be more complex when setting the Oracle password, which usually consists of an alphanumeric special symbol.
However, when you have special symbols, you may have trouble modifying your password or importing the exported data, which is explained in the following context:
This article takes the special symbol "/" as an example
