5 Questions
Explain the applications of Breadth First Traversal (BFS) mentioned in the text.
The applications of BFS mentioned in the text are finding all the lonely nodes, finding the max area of an island, and finding the number of distinct islands.
What are the applications of Depth First Traversal (DFS) mentioned in the text?
The applications of DFS mentioned in the text are solving the maze problem and finding the boundary of a binary tree.
Define the basic terminology related to tree data structures mentioned in the text.
The basic terminology includes 'Node', which is every element of the tree storing actual data and links to other nodes, and 'Link / Edge / Branch', which represents the connection between nodes.
Why are tree data structures useful?
Tree data structures allow quicker and easier access to data due to their non-linear hierarchical nature.
What is the general method of Backtracking and some of its applications mentioned in the text?
The general method of Backtracking is mentioned, along with applications such as solving the N Queens problem, finding the Hamiltonian cycle, and solving the Brace Expansion and Gray Code problems.

Tree Data Structures
- Basic terminology:
- Node: a point in the tree where a branch or leaf meets
- Edge: a connection between two nodes
- Leaf node: a node with no children
- Parent node: a node that has a child node
- Child node: a node that has a parent node
- Root node: the highest node in the tree
- Subtree: a subset of a tree
Tree Data Structures
