In a binary tree, how many leaf nodes can there be at maximum if there are n internal nodes?

In a binary tree, how many leaf nodes can there be at maximum if there are n internal nodes?

Step 1: Understand what an internal node is. An internal node is a node in a binary tree that has at least one child.
Step 2: Understand what a leaf node is. A leaf node is a node that does not have any children.
Step 3: In a binary tree, each internal node can have a maximum of 2 children.
Step 4: If you have n internal nodes, each of these nodes can potentially create new leaf nodes.
Step 5: For every internal node, you can think of it as contributing to the creation of a new leaf node.
Step 6: If you start with 1 internal node, it can create 2 leaf nodes at maximum.
Step 7: If you add another internal node, it can also create 2 more leaf nodes, but one of the previous leaf nodes might become an internal node.
Step 8: The pattern continues, and you can derive that for n internal nodes, the maximum number of leaf nodes is n + 1.
Step 9: Therefore, the formula is: Maximum Leaf Nodes = n + 1.
