Question 3 Construct a Btree for the following set of key values: (12, 75, 10, 99, 25, 21, 9, 19, 22, 74, 82). Assume that the tree is initially empty and values are added in the presenting order. Draw the steps for builing the Btree for the case where the number of pointers, not values, that will fit in one node is five or 2d = 4. Full explain this question and text typing work only thanks

12. Find By Value Runtimes What is the worst case runtime for a "find by value" operation for linked lists and for balanced binary search trees? Pick ONE option Linked List: 0(n^2); Balanced BST: O(1) Linked List: 0(n); Balanced BST: O(log(n)) Linked List: O(n^2) ; Balanced BST: O(log(n)) Linked List: 0(n) ; Balanced BST: O(n)
B+ trees in DBMS plays an important role in supporting equality and range search. Construct a B+ tree. Suppose each node can hold up to 4 pointers and 3 keys. Insert the following 10 keys (in order from left to right): 1, 3, 5, 7, 9, 2, 4, 6, 8, 10 After the insertions, which of the following key pairs resides in the same leaf node? Refer to the previous question. How many pointers (parent-to-child and sibling-to-sibling) do you chase to find all keys between 4 and 7?
