06. Assume that you have built a dense primary B+ tree index on a heap file containing 20,000 records. The key field for this B+ tree index is a 40 byte string and it is a candidate key. Pointers (i.e. record ids and page ids) are (at most) 10 byte values. The size of one disk page is 1,000 bytes . The index was built in a bottom-up fashion using the bulk-loading algorithm, and the nodes were filled up as much as possible. Then there are number levels in the tree.
you need to design, analyze, and implement algorithms to read in a sequence of characters from standard input and maintain the characters in a linked list with no duplicates. When you read in a previously unseen character, insert it at the front of the list. When you read in a duplicate character, delete it from the list and reinsert it at the beginning. The program implements the well-known move-to-front strategy which is useful for caching, data compression, and many other applications where items that have been recently accessed are more likely to be re-accessed. Requirements: The program should read a sequence of characters. The program should insert unseen character at the front of the list. The program should check if the character is not in the list to be inserted at the front of the list. The program should delete a duplicate character and delete it from the list and insert it at the beginning of the list. The program should check if the character is already in the list and…
2. Suppose the list of letters A, B, C, E, F, and G are stored in a contiguous block of memory cells. What activities are required to insert the letter D in the list, assuming that the list's alphabetical order is to be maintained?
Problem Given the target file f0 and candidate files f1-f20, there is an identical copy of f0 among the files f1-f20. Write a python program to perform the following tasks: · Read in each file and calculate the hex hash values by using SHA3 function with the length of 512 for all the given files f0, f1-f20. · Save the hex hash values of each file as a new line in a .txt file named hash.txt file. · Read hash values from hash.txt and compare them to find the identical copy of f0 among f1-f20. · Write the finding result (the matched file name) back to hash.txt Submission • Name your project fileHash.py and submit both fileHash.py and hash.txt on Blackboard. • The program should be properly documented. • The program should have user friendly Input/Output design • Duplicate work (or obviously similar one) will result in an F grade in the course. Grading 1. Include comments as specified in the course syllabus. (10%) 2. Source code and results. · Correctness (70%) · User-friendliness…
Implement and demonstrate a disk-based buffer pool class based on the LRU buffer pool replacement strategy. Disk blocks are numbered consecutively from the beginning of the file with the first block numbered as 0. Assume that blocks are 4096 bytes in size. Use the supplied C++ files to implement your LRU Buffer Pool based on the instructions below. Implement a BufferBlock class using the supplied BufferBlockADT.h Your Buffer Block must inherit BufferBlockADT or you will not get credit for your work. All BufferBlockADT virtual functions must be implemented in BufferBlock Block Size: 4096 bytes Add an instance variable to your buffer block implementation to store the block id; i.e., “int blockID.” Implement a Buffer Pool by inheriting BufferPoolADT (BufferPoolADT.h) – implement all of BufferPoolADT’s functions Your buffer pool should consist of 5 buffer blocks Your buffer pool should manage the buffers using the LRU strategy Your buffer pool should be named LRUBufferPool and…
What is the correct order for converting the source code into an executable file? Answer Choices: a. Preprocessing -> Compiling -> Assembly -> Linking b. Preprocessing -> Linking -> Assembly -> Compiling c. Compiling -> Preprocessing -> Linking -> Assembly d. Compiling -> Preprocessing -> Assembly -> Linking
RCS adopts a reverse delta approach for storing multiple versions of a file. For example, assume a file has three revisions, 1.1, 1.2, and 1.3, RCS stores the file as of version 1.3, then, the differences between 1.2 and 1.3, and the differences between 1.1 and 1.2. When a new version is created, say 1.4, the difference between 1.3 and 1.4 is computed and stored, and the 1.3 version is deleted and replaced by 1.4. Explain why RCS does not simply store the initial version (in this case 1.1) and the differences between each successive version.

1. Given that F is a direct file with n = 2000 records and that the records are stored in orderof their keys. Determine how any record reads it would take to locate a particular record using:a. Sequential search (average case)b. Binary search (worst case)c. (open) hashing with 200 buckets (average case)d. (open) hashing with 400 buckets (average case) 2. Write the declarations to create a data type called: DICTIONARY that represents an openhashing scheme with 20 buckets
Please write in C/C++Write a program that spawn 2 thread: a producer and a consumer The producer thread MUST open an input file and repeatedly copy values to a CIRCULAR BUFFER The consumer should open an output file and repeatedly copy values from the same circular buffer to the file. If the producer is unable to write to the buffer (because it does not contain enough empty elements), or if the consumer is unable to read from the buffer (because it does not contain enough unread items), then it should proceed to the next iteration, choosing a new random number of bytes to copy.
