Questions & Step-by-Step Solutions
Which of the following statements about Red-Black trees is true?
Step 1: Understand what a Red-Black tree is. It is a type of binary search tree that has specific properties to ensure balanced height.
Step 2: Learn the properties of Red-Black trees. One important property is that no two red nodes can be adjacent (i.e., a red node cannot have a red child).
Step 3: Realize that because of this property, if a node is red, its children must be black. This means you can only have one red node in a row.
Step 4: Conclude that the statement about Red-Black trees having a maximum of one consecutive red node is true.
