In a Red-Black tree, what happens when a red node is inserted?

In a Red-Black tree, what happens when a red node is inserted?

Step 1: Insert the new red node into the Red-Black tree as you would in a regular binary search tree.
Step 2: Check if the parent of the new red node is also red.
Step 3: If the parent is red, this violates the Red-Black property that states a red node cannot have a red parent.
Step 4: To fix this violation, check the color of the uncle node (the sibling of the parent).
Step 5: If the uncle is red, change the parent and uncle to black and the grandparent to red, then repeat the check from the grandparent.
Step 6: If the uncle is black or null, perform a rotation (left or right) and recolor nodes to restore the Red-Black properties.
