Binary Tree Traversal A traversal is a process that visits all the nodes in the tree. Since a tree is a nonlinear data structure, there is no unique traversal. We will consider several traversal algorithms with a group in the following two kinds: depth-first traversal breadth-first traversal ...

In the previous chapter, you looked at a basic tree where each node can have many children. A binary tree is a tree where each node has at most two children, often referred to as the left and right children. Binary trees serve as the basis for many tree
First of all, we need to learn two structures: (1) Binary Tree (2) Deque abinary treeis atree data structurein which each node has at most twochildren, which are referred to as theleft childand theright child. adouble-ended queue(abbreviated todequeis anabstract data typethat generalizes...
