I have read this mode twice because I don't quite understand it, but I still don't understand it. By writing code, self-understanding is to redecorate the object. By inheriting the same base class. Instead of adding additional classes

There is a 16-digit integer that calculates the sum of every four digits in the binary. For example: int a = 1111 1111 1111 1111; (this is a binary system) Int sum = 1111 + 1111 + 1111 + 1111. (This is 1111 of the 10 hexadecimal value) [Cpp]#

1. The Builder mode is called the builder mode, which creates a complex class through different objects. The Builder mode also solves the following problems: When the objects to be created are complex (usually composed of many other objects ), we

The merge operation (merge), also called the merge algorithm, refers to the operation that combines two sorted sequences into one. If there is a series of {6,202,100,301, 8, 1} initial states: [6] [202] [100] [301] [38] [8] [1] comparison times I = 1

A coroutine is a collaborative program. The idea is that a series of mutually dependent coroutines use the CPU in sequence, with only one coroutine working at a time, while other coroutine is in sleep state. The coroutine can pause execution at a
