CSC 385 –Assignment 4 –Faster SortingAlgorithms .This problem is taken from a hackerrank programming challenge. The problem is tagged as having medium difficulty in hacker rank:(https://www.hackerrank.com/challenges/fraudulent-activity-notifications) Problem Description—Fraud DetectionHackerLand National Bank has a simple policy for warning clients about possiblefraudulent account activity. If the amount spent by a client on a particular day is greaterthan or equal to 2 ×the client's medianspending for the last d days, they send the client a notification about potential fraud. The bank doesn't send the client any notificationsuntil they have at least d prior days of transaction data.Given the value of d and a client's total daily expenditures for a period of n days (where n>d) write amethod which returns the number of times the client will receive a notification over all days.Note: Your algorithm time efficiency should not exceed O(nd) where n is the total number of daily…

4) Question 2 asked you to compute the number of possible passwords with various numbers of characters. However, it seems more likely that most people will choose actual words for their password. According to the website wordfinder.yourdictionary.com, the English language has approximately 23,000 six-letter words. a) Assume that a password must be at least 8 characters long and include at least 1 digit and at least 1 special character (again, assume there are 30 of these that are allowed). If people form their password by taking an English word of exactly 6 letters (assume that this password is not case-sensitive) and then adding (in either order) a digit and a special character (e.g flames#1), how many passwords would be possible? (Hint: Find the number of passwords with 6 letters followed by a digit and a special character, then exchange the order of the last two characters.) b) How does your answer change if we assume passwords are case-sensitive and the password must…
Hi, I need help witht the following HW.. Recent changes in privacy laws have disallowed organizations from usingSocial Security numbers to identify individuals unless certain restrictionsare satisfied. As a result, most U.S. universities cannot use SSNs as primarykeys (except for financial data). In practice, Student_id, a unique identifierassigned to every student, is likely to be used as the primary key rather thanSSN since Student_id can be used throughout the system.a. Some database designers are reluctant to use generated keys (also knownas surrogate keys) for primary keys (such as Student_id) because they areartificial. Can you propose any natural choices of keys that can be used toidentify the student record in a UNIVERSITY database?b. Suppose that you are able to guarantee uniqueness of a natural key thatincludes last name. Are you guaranteed that the last name will not changeduring the lifetime of the database? If last name can change, what solu tions can you propose for…
A school is upgrading its website and will require students to create a password to access theirmarks online. In order to create secure passwords, students will be required to meet certainconditions.a. Determine the total number of possible 4-character passwords that can be created using eachof the following requirements: the digits 0 to 9, where the first digit must be even and last digit must be odd, and wheredigits can be repeated
Bitcoin mining is also known as proof-of-work because in order to create a valid block, the miner has to spent a significant amount of computational work to figure out a nonce. Therefore, that the hash of the nonce and the block to be proposed is adequately small. Which of the following is NOT a reason to include proof-of-work in the designs of permissionless blockchains? 1. To randomly select nodes in proportion to their computing power. 2. To make mining so costly that miners have incentives to not create invalid blocks. 3. To make it impossible for one miner to act like many different miners. 4. To allow nodes to compete for the right to create blocks
