Question: Which operation is NOT performed during the insertion in a Red-Black tree?

Options:

  1. Coloring the nodes
  2. Rotations
  3. Rebalancing
  4. Sorting the nodes

Correct Answer: Sorting the nodes

Solution: 

During insertion in a Red-Black tree, nodes are colored, rotations may occur, and rebalancing is done, but sorting is not part of the insertion process.

Questions & Step-by-Step Solutions

Which operation is NOT performed during the insertion in a Red-Black tree?
  • Step 1: Understand that a Red-Black tree is a type of binary search tree that maintains balance through specific rules.
  • Step 2: Know that during insertion, a new node is added to the tree just like in a regular binary search tree.
  • Step 3: After adding the new node, it is colored either red or black according to Red-Black tree rules.
  • Step 4: Check if the tree maintains its properties. If not, rotations (rearranging nodes) may be needed to fix the tree.
  • Step 5: Rebalancing is done to ensure the tree remains balanced and follows Red-Black tree properties.
  • Step 6: Understand that sorting is not done during insertion; the order of nodes is already determined by the binary search tree property.
