Question 1

How do you insert a node into a binary search tree?

Accepted Answer

To insert a node into a binary search tree, you start at the root and compare the new value with the current node's value. If it's smaller, you go to the left child; if it's larger, you go to the right child. You repeat this process until you find an empty spot where the new node can be inserted.

Question 2

What are the three cases to consider when deleting a node from a binary search tree?

Accepted Answer

When deleting a node from a binary search tree, you need to consider three cases: the node has no children, the node has one child, or the node has two children. Each case requires a different approach to maintain the binary search tree property.
