Problem 6: Red black trees. Let D be a data structure on the set of positive integers,which supports the following operations:- Insert(D, x): insert x in D.- Remove(D, x): remove x from D.- Find(D, x): find x in D.- Count(D, x): returns the number of elements in D that are larger then x.We would like to implement D by using red black trees. Describe how can we modify a redblack tree such that all four operations have time complexity O(log n), where n denotes thenumber of elements in the structure. Elaborate why time complexity of all four operationsis O(log n).

TREE-DELETE is broken into three cases.Case 1: z has no children.• Delete z by making the parent of z point to NIL, instead of to z.Case 2: z has one child.• Delete z by making the parent of z point to zís child, instead of to z.Case 3: z has two children.• zís successor y has either no children or one child. (y is the minimumnodeówith no left childóin zís right subtree.)• Delete y from the tree (via Case 1 or 2).• Replace zís key and satellite data with yís.✄ Determine which node y to splice out: either z or zís successor.
when the successor is the left child of the node to be deleted. What are the steps followed by algorithm for performing this operation.
