- I need to draw the state of the memory using the specifications below and provide answers to the question. I have to do it similar to the one shown on the board if that makes any sense. All parameters are passed by reference. The language uses static scoping. What are the values of j and k after the execution of the program?arrow_forwardPlease help me wiht this and show the answer on hand writtenarrow_forwardCan you find the shortest path tree starting from vertex 3 to all other vertices for the graph below using BFSarrow_forward
- Can you find shortest path from vertex 3 to all other vertices for the graph below.arrow_forwardcan 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_forward
- The 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_forwarda) 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)?

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_forwardb) Below is an example of a B+ tree. Add an element with key 19 and then delete an element with key 1.
