What is the time complexity for deleting an element from a Red-Black tree?

Step 1: Understand what a Red-Black tree is. It is a type of self-balancing binary search tree.
Step 2: Know that in a binary search tree, elements are organized in a way that allows for efficient searching, inserting, and deleting.
Step 3: Recognize that the Red-Black tree maintains balance through specific properties, which helps keep the tree height low.
Step 4: Realize that the height of a Red-Black tree is always O(log n), where n is the number of elements in the tree.
Step 5: Understand that deleting an element involves finding the element and then restructuring the tree to maintain its properties.
Step 6: Since the height of the tree is O(log n), the time it takes to delete an element is also O(log n).
