problem : Print the binary tree from top to bottom, and the nodes in the same layer are printed to one line from left to right. For example:
Print results:
8
6 10
5 7 9 11
Analysis: In order to print each row of the two-fork tree to a single line, we need two variables: One variable represents the number of nodes that have not been printed in the current layer, and the other represents the next level of nodes.

First, fork introductory knowledge
A process that includes code, data, and resources assigned to the process. The fork () function creates a process that is almost exactly the same as the original process through system calls, where two processes can do exactly the same thing, but two processes can do different things if the initial parameters or incoming variables are different.
Once a process calls the
When a thread calls a function fork, the entire process address space is copied to the child process, Copy-on-write is mentioned in section 8.3. A child process is a process that is completely different from the parent process, but if neither the parent process nor the child process modifies the contents of the memory, the memory page can be shared between the parent process and the child process.By inheriting the entire address space of the parent pr
In Unix systems, the only way to create a new process is to call the fork system. The process called fork is called the parent process, and the newly created process is called the child process. Syntax format of system call:
PID = fork ();
When the fork is returned from the system call, the two processes have the same

Usage Analysis:Fork () This function, it can be said that the name of the person, it is well known that fork the word is meant to fork, the foreigner to take the academic name when there will always be some pictographic ideas, so there is ~The fork () function is a bifurcation function in computer programming. That is, a parent process will create a child proc
When the thread calls fork, it creates a copy of the whole process address space for the child process. Recall interval.
By inheriting copies of the entire address space, the child process also inherits the status of all mutex, read/write locks, and condition variables from the parent process..If the parent process contains multiple threads and the child process does not call exec immediately after the fork
(1) Fork system call DescriptionThe fork system call is used to create a new process from an existing process called a child process, and the original process is called the parent process. The fork is called once, returned two times, and the two returns return their respective return values, where the return value in the parent process is the process number of th
Fork is one of the most difficult concepts to understand: it executes once but returns two values.First, let's look at the prototype of the fork function:# include # include pid_t fork (void);return value:Negative number: If there is an error, fork () returns-1, no new process is created at this time. The initial proce
Basic ConceptsThe level of the node is defined from the root and the root is the first layer and the child of the root is the second layer.Height of the binary tree: the maximum level of the node in the tree is called the depth (Depth) or height of the tree.Two fork TreeIn computer science, a binary tree is an ordered tree with a maximum of two subtrees per node. Usually the root of the subtree is referred to as the left subtree and right subtree. A b

If I can't understand it, I'm bacchanalian .a wonderful thing about a fork call is that it is called only once, but it can return two times, and it may have three different return values:1) In the parent process, fork returns the process ID of the newly created child process;2) in the sub-proce

For a single CPU, only one process occupies the CPU at each specific time, but there may be multiple active (waiting for execution or continuing execution) processes in the system at the same time.

The only way to create a new process in Linux is to use the fork () function. The fork () function is a very important function in Linux, and there are some differences from previous functions, because the fork () function looks like it executes once but returns two values.
