The topic means that you need to use and check the set and then perform enumeration like Vertex coloring. It is very simple to enumerate, but the brute force will not have to re-learn.

ProcessWhat is it?JobWhat is it? InLinuxEverything running on the system can be called a process. For example, a simple helloworld program, input the ls command on the terminal, and so on.
A normal running process is called a job. A job can start multiple processes. For example, the job ls-lrt | grep *. txt starts two processes.
Commands related to processes and jobs include kill, disown, wait, fg, bg, and jobs.

Str. rstrip ([chars])
Returns a copy of str. The character at the end is removed. spaces are removed by default. chars indicates the removed character set.

The string is split into a list using the line delimiter. When keepends is set to True, the line Delimiter is retained after the string is split. For the line delimiters that can be recognized, see the official documentation.

to execute a program for a long time. If the program is executed in the foreground, other operations may not be performed, it is best to put it in the background for execution. 18. fg: The fg command is executed on the foreground. If a program runs in the background, you can use the fg command to move the program from the background to the foreground for executi

11. fg, bg
Sometimes, the command takes a long time to complete. In this case, we can run the 'bg 'command in the background, while 'fg' can be used in the foreground.
We can start a program in the background through:
find .-name *iso >/tmp/res.txt
A running program can also be run in the background by combining the "CTRL + Z" and "bg" commands.
1. function prototype: The function prototype describes the function-to-compiler interface, that is, it informs the compiler of the type of the function return value and the number of parameter types.
2. pointer and const:
There are two kinds of const usage: one is to point the pointer to a constant object (the pointer refers to const), and the other is to declare the pointer itself as a constant (the pointer is const ).
