Describe the difference between pre-order and post-order traversal in binary trees.
Pre-order traversal processes the root after its children, while post-order processes the root before its children.
Pre-order traversal only processes leaf nodes, while post-order processes all nodes.
Pre-order traversal processes the root before its children, while post-order processes the root after its children.
Both pre-order and post-order traversals process the root at the same time.

What is the purpose of a depth-first search (DFS) in graph traversal?
To identify cycles in a directed graph.
To find the shortest path between two vertices.
To calculate the total weight of all edges in a graph.

Explain how breadth-first search (BFS) works in graph traversal.
Breadth-first search (BFS) explores a graph level by level using a queue to track nodes.
BFS uses a stack to explore nodes in depth-first order.
BFS only visits nodes that are directly connected to the starting node.
