Prоblem 2 (5 pоints) – B-Tree (1) (1 pоint) Explаin how to find the minimаl key stored in а B-tree; (2) (2 points) Give the pseudo code of the predecessor function B-Pred(x, k) of a given key k stored in node x of a B-tree; (3) (2 points) Show the process of inserting the following keys into a B-tree with degree t = 2 in the given order using the algorithm in our Textbook: Your Family Name, FIU, SCIS, COP5407, Final, Exam, and Spring2025 (you only need to show the relative positions of the keys without drawing the nodes).
