Concept explainers
What data types are required for a switch variable? If the keyword break is not used after a case is processed, what is the next statement to be executed? Can you convert a switch statement to an equivalent if statement, or vice versa? What are the advantages of using a switch statement ?

- can you draw the shortest path tree using BFS for the following directed unweighted graph?arrow_forwardWhat is the shortest path from vertex 3 to all other vertices:Which graph algorithm can solve the problem most efficiently(the quickest runtime)How could the same algorithm if the graph had edge weights? (create intermediate nodes)arrow_forwardThe difference between (1) a database management system (DBMS) and (2) a database, is: a. The first refers to a complete accounting system, the second refers to a subset of that b. The first is program software, the second is proprietary data and related files c. The first is hardware, the second is software d. Nothing—these terms are synonyms..arrow_forward
- a) An example of the linear hash index is given below. Every time a new overflow page is added, the bucket pointed by Next is split, and Next is incremented by one. Show the index state after adding the keys 39, 25, and 29. hi ho Level=0, N=4 000 00 0*8* 001 01 17*33* 010 10 6*26* 42* 011 11 7* 11* 15* 23* 100 00 4* 12* 20* 101 01 5* 13* 21* 37* Nextarrow_forwardWhat would be the runtime (big-O asymptotic notation) of Dijkstra’s algorithm if it is implemented based on an unsorted minimum priority queue in terms of vertices (v) and edges (e)? Please show all steps including the runtime of each step of the algorithm.arrow_forwarda) An extendable hashing index is given below. Present the state of the index after adding the keys 21, 25, and 29.

Which buckets in the index above (after inserting 21, 25 and 29) have a global depth equal to the local depth? c) Describe the bulk loading algorithm for B+ trees. What are the differences to using a simple B+ tree add operation?arrow_forward

- Data environment The SPJ company manages the orders of the parts from the suppliers for the projects that run at other companies. A project is described with the project identifier, name, company where the project takes part, budget, start date, and the duration of the project. A part is presented with the part identifier, name, and price. A supplier is described by the supplier identifier, name, address, city and phone number. For each order of a product from a given supplier for a given project, we store the number of parts ordered, the price of the order, the date, and the comment. The information system SPJ includes the following tables. Parts pid, name, price ); Projects( jid, name, company, budget, start, duration ); Suppliers sid, name, address, city, phone ); Orders oid, pid, jid, sid, quantity, price, date, comment );arrow_forwardData environment The SPJ company manages the parts orders from the suppliers for the projects that run at other companies.
