Question: What is the time complexity for searching an element in a Red-Black tree?

Options:

Correct Answer: O(log n)

Solution:

Searching for an element in a Red-Black tree takes O(log n) time due to its balanced nature.

What is the time complexity for searching an element in a Red-Black tree?

Step 1: Understand what a Red-Black tree is. It is a type of binary search tree that keeps itself balanced.
Step 2: Know that in a binary search tree, searching for an element involves comparing the target value with the values in the nodes.
Step 3: Realize that a balanced tree means the height of the tree is kept low, which helps in searching quickly.
Step 4: In a Red-Black tree, the height is approximately log(n), where n is the number of nodes in the tree.
Step 5: Since searching involves traversing from the root to a leaf, the time taken is proportional to the height of the tree.
Step 6: Therefore, searching for an element in a Red-Black tree takes O(log n) time.
