Binary Search Trees: BST Explained with Examples

Binary Search Tree and Its Operations in Data Structure | Simplilearn

SOLVED:A(left, right) child of a vertex in a binary tree is the root of a (left, right) subtree of that vertex. A binary tree is a full binary tree if each vertex has either two nonempty children or two empty children (a vertex with two empty children is called a leaf.) Draw all full binary trees on seven vertices.

Introduction to Binary Tree - GeeksforGeeks

SOLVED:We defined a binary search tree so that keys equal to a node's key can be in either the left or right subtree of that node. Suppose we change the definition so that we restrict equal keys to the right subtree. What must a subtree of a binary search tree containing only equal keys look like in this case?
