Binary search using pointers
WebBinary Search Tree is similar to a graph but with some special properties, a BST (Binary Search Tree) has a node, left pointer and a right pointer. They allow fast lookup, addition and removal of items, and can be used to implement either dynamic sets of items, or lookup tables that allow finding an item by its key. WebOct 26, 2024 · In a binary tree, to do operator++. We need to know not only where we are, but also howwe got here. One way is to do that is to implement the iterator as a stack of pointers containing the pathto the current node. In essence, we would use the stack to simulate the activation stack during a recursive traversal. But that’s pretty clumsy.
