- 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 bucketsA.) This script, named build.sh gets as argument the path to a folder where to find a source file and builds the executable. B.) This script named script02.sh and take two arguments: a string to look for, and a path to the root folder to start the search from. The script should then explore recursively the folder hierarchy starting from the folder located at the path given as argument. At each folder encountered through the recursive search, the script should build a list of all text files in the folder and send this list, along with the target and the folder’s path, in a call to prog02 ( c program). The output of your script should have the following format: Recursive search for target <target> starting at <path> Search depth: <depth> Total number of folders: <number> Total number of text files: <number> <output produced by the C program>Write comparators for the typeFile to order by increasing/decreasing order of file size, ascending/descending orderof file name, and ascending/descending order of last modification date. Use thesecomparators in a program LS that takes a command-line argument and lists the filesin the current directory according to a specified order, e.g., "-t" to sort by timestamp.Support multiple flags to break ties. Be sure to use a stable sort
- Create a TST client with a static method that takes as command-line arguments an int value L and two file names and computes the L-similarity of the two documents: the Euclidean distance between the frequency vectors defined by the number of occurrences of each trigram divided by the number of trigrams. Include a static method main() that accepts an int value L as a command-line argument and a list of file names from standard input and prints a matrix displaying the L-similarity of all document pairs.The questions should be solved using Linux Bash Scripting. In the file there should be solution code and one/two screenshot for running of program. Student id and names should be written inside the file. The assignment should be sent as PDF.

- Define a function deleteProp that has 2 parameters: obj an object to update keyName, a string - a key name to delete from the object deleteProp should delete the property with the key of keyName. deleteProp should return the object that was passed in (not a “copy” or different object with the same key/value pairs) example const wallet = { color: 'Black', hasCash: true } deleteProp(wallet, 'color'); => { hasCash: true } const house = { sqFt: 1500, isOccupied: true } deleteProp(house, 'isOccupied'); // => { sqFt: 2000 } javascriptImplement a blog server in C 1. Implement get of all posts (GET /posts), and individual post (GET /post/1) 2. Implement creation of post (POST /posts). Allow the user to enter their name, but check that they are a valid user in db. Do error checking! The user should not specify the post id; that should come from the database. 3. Write three html files to test this; serve them with the blog server: index.html shows the list of posts with a link to each. post.html shows a post. publish.html allows the creation of a new post. Link these together as a user would expect!2. Start with an empty buffer pool of size 4 pages again. This time use this access pattern:♯SAGLIKLIMUTLUBAYRAMLAR♯. At the end of accessing all the pattern, what is the content ofthe buffer pool (write in alphabetical order)? Use the LRU algorithm as the buffer replacementpolicy.

Stores elements based on Array Data StructureComputer ScienceA restaurant requires WAIT ADT to help waiter to wait tables. Theapplication is required to provide functions to add a food item to the WAITlist, remove an item from the Wait list, size of the list i.e., the food itemsordered, and know if item is already in the list. The WAIT ADT access timeshould be O [1]. Provide implementation details with your choice of datastructure and the operations with justification of the constant access time.Implement search food in the added Wait list in C.Python question: This requires knowledge of gensim NLP package.
