If you might have noticed, we have called return search(struct node*) four times. When we return either the new node or NULL, the value gets returned again and again until search(root) returns the final result. If the value is found in any of the subtrees, it is propagated up so th...
Binary Search Trees A Binary Search Tree (BST) is a type ofBinary Tree data structure, where the following properties must be true for any node "X" in the tree: The X node's left child and all of its descendants (children, children's children, and so on) have lower values than X'...

This is a project in which we learned about the details, advantages, and disadvantages of using trees as data structures. We learned about how to qualify trees as well as how to traverse them. Throughout the project, we implemented binary, binary search, AVL, and Max Binary Heap trees. ...
