Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

Hash Search Design a hash table which the phone number is the key word and can be used to do search. The phone number is looked on as key and thus the hash function should be designed based on it. Basic Requirements 1) Each record contains 3 data items, i.e. name, sex and phone number. 2) Read the datum from txt file, use phone number as the key to design hash function, using open addressing method to solve conflicts. Build hash table and show highest number of hashes. There are 450 records in total, and the size of hash table is defined as 467. The maximum number of hashes is required to be no more than 80 3) When the user input a phone number, your program should do hash search based on this number. If the number dose exist then the corresponding information should be shown, and the number of hashes should be shown as well. If the number does not exist in the table, still show the number of hashes and the information My data LiuJing Female 13814231733 WangAnqi Male 15855129526…

Password Cracking Each student should be able to access* one PassXX.hash file. This file contains 4 unsalted md5 password hashes (md5 is commonly used for hashing passwords, though it is a bit weak for modern use. It is very important to salt passwords before hashing them, since leaving them unsalted makes them easier to crack. However, many sites fail to do this). Your assignment is to use Hashcat (or another password cracking or password "recovery" tool) to retrieve the original passwords from the hashes, and submit the password/hash pairs. Each set of hashes contains 1 very easy password and 3 slightly challenging passwords of differing format. Link to hashcat: https://hashcat.net/hashcat/ Note: You will also need one or more dictionaries to perform a dictionary attack. *access: Files are accessible based on your last name. You should see a large number of files that are not accessible due to your account having a wrong last name, and one file that is accessible that lacks…

Consider a system of three independent, periodic real-time tasks: T1= (4, 3), T2 = (12,7), and T3 = (8, 5). Construct the schedule for these tasks in the interval [0, 24) with q=1 on twoprocessors with PF. Note that there are many PFair algorithms, while PF is one of them. PF prioritize subtasks by deadlines, and break ties by inspecting future subtask deadlines. Also, if a currently-executing job ties with a newly- released job, then continue executing the currently-executing job; break any other ties by task ID (T1 = highest, T3 = lowest). a. Show all sub jobs’ releases and deadlines for (the first job of) each task. Note that q=1 so each sub job should have execution requirement of 1b. Show the PF schedule.c. Will this task set be schedulable with q=2? Please explain.
