Problem 2 (5 points) – B-Tree (1) (1 point) Explain how to find the maximal key stored in a B-tree; (2) (2 points) Give the pseudo code of the successor function B-Succ(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 Fall2024 (you only need to show the relative positions of the keys without drawing the nodes).

When Kara’s Glass Shop received a rush order before an upcoming holiday weekend, Jennifer persuaded her employees to work overtime by buying them pizza and passing out gift cards throughout the weekend. Jennifer was engaging in which of the following functions of management?

A government inspection has required your company to upgrade the safety equipment in the manufacturing process of ice cream. What dimension of the external environment has influenced these upgrades?

Problem 4 (8 points) – Graph Algorithms (Shortest Paths and Dynamic Programming) A highway system connects major cities in a country. Some cities are directly connected through highways Others may be reached via other cities. The distances between cities directly connected highways are known. (1) (1 point) Abstract the highway system as a weighted graph G (nodes and edges) with w (weights); (2) (2 points) Describe (no pseudo code) an efficient algorithm to find the shortest distances from a given city s to all other cities (you can  mention some known algorithm in your description if it works). What is the time complexity? (3) (5 points) Dynamic programming technique can be used to find the shortest distances between all pairs of cities: (a) formulate the recurrence relationship of the shortest distances between cities  i and j using the shortest distances of sub-structures; (b) write pseudo code to implement the recurrence relationship efficiently; and (c) analyze its complexity.
