10 Questions
Which traversal method starts by visiting the root of the tree itself and then traverses the tree by first exploring all the branches on the left side until reaching their deepest nodes, and then repeating the process for the nodes on the right side of the root?
Preorder traversal
Which traversal method moves from the leftmost element to the rightmost element in a tree?
Inorder traversal
Which traversal method goes to the deepest node on the left side of the tree, then visits the right child, and finally visits the parent node?
Postorder traversal
Which of the following is NOT a property of a tree?
It can have values of any data type
Which of the following is NOT a method to solve a problem with the depth-first search pattern?
Breadth-first search
What is the fundamental characteristic of the depth-first search pattern in a tree?
It travels as far as possible along each tree branch before exploring the others
Which pattern is commonly used to find products in a price range?
Depth-first search
What is the purpose of performing a variation of preorder traversal on the binary search tree in the product price range problem?
To add the value to the output array if it lies in the range
Which real-world problem uses the depth-first search pattern for finding a route between a start and destination point?
Solving mazes
What is the strategy used in solving mazes using the depth-first search pattern?
