In binary tree (b), nodes 4, 5, 6, and 7 all have no children.Nodes that have no children are referred to as leaf nodes. Nodes that have one or two children are referred to as internal nodes. Using these new definitions, the leaf nodes in binary tree (a) are nodes 6 and 8; ...

A binary heap is a tree created using a binary tree. It can be seen as a binary tree with two additional constraints: Shape property: A binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and, if the last...

Breadth-first traverse iterative traverse of tree.This is an old one: instead of using a stack (implicit function call stack, or an explicit data structure), the algorithm uses a FIFO queue to keep track of its place in the traverse of the tree....
This is because we are recursively constructing the tree and maintaining call stack space for each node. In the worst case, the recursion depth would be equal to the height of the tree, which is O(n) for a skewed tree. Additionally, we are not using any extra data structures that grow...
