The easiest way to implement theinOrdertraversal algorithm in Java or any programming language is by using recursion. Since the binary tree is a recursive data structure, recursion is the natural choice for solving a tree-based problem. TheinOrder()method in theBinaryTreeclass implements the logi...
A binary tree is a data structure in which each element has at most two children, which are referred to as the left child and the right child. The top element of the tree is the root node, whereasthe children are the interior nodes. However,if a node has no child, it’s called a ...

2. Binary Tree A binary tree is a recursive data structure where each node can have 2 children at most. A common type of binary tree is abinary search tree, in which every node has a value that is greater than or equal to the node values in the left sub-tree, and less than or ...

Binary search trees have one important property: everything in the left subtree is smaller than the current node, and everything in the right subtree is larger. This lets us look things up in O(lg(n)) time (as long as the tree is balanced).
