How to write c code for a binary tree how to#

It is not necessary to consider the insertion between the nodes, for example to organize a tree or develop code for balancing the tree. In this case, in order to understand the principle of its construction does not need a ton of code. Well, maybe N-dimensional tree will be slightly more difficult to implementвЂ¦ Or is there some divine-cosmic language used? If you think, it is difficult to plant a tree вЂ“ here's the obvious unbelievable. Yggdrasil famous could well be established here so that's 14 th strings in C ++. It is all! What do you think? Tree ready. The above code carries a kind of search, but not for result, and to find a place for the element. Used by the way in artificial intelligence. Recursive call functions, to pass through the column, tree or other type of hierarchical structure вЂ“ It is the easiest way. Hierarchy is very friendly with recursion.

The same is true for the left branch, if the data value less.

If the transmitted data is greater than the current node data вЂ“ try to build it right branch, or if it is already there just to pass through it.

If a branch node is not created вЂ“ create it, fill the data and specify NULL (0) for its branches.

Note: The functions of the three basic conditions: The simplest code tree construction (with a hierarchical structure) It will look like: so вЂњ4вЂќ already go from eight not right, and left. Further to the right to meet the number of 8. Pass the вЂњ2вЂќ and вЂњ3вЂќ, for 4 More meaningfully. Since it is more, program should look, Do you have the right root branch. From unit to go through a deuce to triples and just grow right branch.ДЄfter eight is 4. After deuces no branches, It means it is necessary to create a branch to the right to assembly вЂњ2вЂќ. The program should work through them, check: 3 more 1? вЂ“ Yes. So at the root to grow to the right branch ( RightBranch) in our case. According to the code of its value is greater than. The second character вЂ“ вЂњ2вЂќ It will be compared with the root. The first character will become the root, respectively. It is necessary to sow the seed, so it grew. First, the program sees, a tree without roots. How should the work program? Take symbols вЂњ12384вЂќ from a string. With the same success it is possible to write a string вЂњThey killed KennyвЂќ. Although I took into digital characters string, it does not matter. Units and sheets will contain characters, on codes of characters will also determine the right or to the left to construct tree. Common string C, which will raise the branches. Although of course can be and Feedback, if you really want. In dynamic lists two pointers are usually associated next and previous elements, in this case a tree with no need, because the, usually, pass on the tree is a root. For this we need the structure of, described like a dynamic list: The data field and two pointers to the left and right branches. The rule is simple, from him, and we will build. The basic rule of the formation of a binary tree in C ++: If the node is greater than the added вЂ“ added the right branch, otherwise a left branch. The main thing is not to stumble on this graph, which are the Countess. You can type in a search word вЂњGraphвЂќ and read. This can be found in Wikipedia, what they are. This is also a large amount of information.

I will not go into the classification tree. But not more than two.ДЄn ordinary tree nodes in branches can be. Hence its name вЂ“ вЂњbinaryвЂќ so вЂњbinaryвЂќ, i.e. binary tree вЂ“ this is a tree, wherein at threads may be no more than two leaves or twigs.

Leaves вЂ“ it hosts, which do not point at anyone, they do not have branches. The tree consists of branches (knots) and leaves (elements). Incidentally lists this particular kind of tree. What tree do? This is a set of data, which point to other data. It is no one but academics are not interested, and in the foreseeable practical too thin. I will not go into the jungle of mathematical horrible Tartarus.

About it it is possible to argue long and hard, and did not come to a common denominator, clearly shows that such a hierarchy and how to work with it, for some canons in the sense of. The program to perform in-order recursive traversal is given as follows.At all, i must admit, that the theme of hierarchical structures is very wide. The inorder traversal of a binary search tree involves visiting each of the nodes in the tree in the order (Left, Root, Right).ДЄn example of Inorder traversal of a binary tree is as follows.

It involves checking or printing each node in the tree exactly once. Tree traversal is a form of graph traversal.
