Binary search tree insert and delete in c
I also made the intro clearer. If you are deleting a leaf node, you must remove the link from the parent of that node to the node itself. People prefer different languages. It also acts differently than the upper image the example deletes the minimum of the right side, where the image deletes the max of the left side. Please include details about your problem, to help other editors.
From the B-Tree article: It is confusing that the article starts by claiming that equal nodes should always be in the right subtree, while the example image puts equal nodes such as the seven, which equals the root in the left subtree. Then, the root node is deleted from memory and then dequeued from the list.
I think it is more precise. Making a distinction between less-than and comparison functions is language-specific; in languages with operator overloading, it can lead to circular definitions because less-than in fact has to be implemented in terms of what this paragraph calls a "comparator". WikiProject Computing Computing articles Information technology portal. The symbol TreeNode is used in the article twice in different sense. Hi, What do you think of adding an observations section with regard to the data structure?

I may have read it wrong. I worked on understanding the code in the article and found some issues. Pseudocode should be more than enough, this is an encyclopedic article, not a coding cookbook. I'm just wondering whether the example code for Deletion is correct
Blocks of code don't really help with this objective. Depending on which side of a node the equal values go to left or rightyou can only base this deletion schema in predecessor OR sucessor not arbitrary. Then, the root node is deleted from memory and then dequeued from the list.
