- Is it feasible to circumvent access control by taking certain steps?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…Authorization lists should be encrypted and secured since they are so vulnerable to manipulation. Imagine if someone messed with these files without meaning to.

- Implement the one-time pad encryption scheme in Microsoft Excel. Your worksheet should look as follows: For Encryption: - Have the message occupy adjacent cells in one row, with one bit of the message in each cell. Align the key (the one-time pad) with the message in the next row. Note that the key should be of the same length as the message. In the next row, enter a formula that computes the ciphertext. Decryption is similar: - Have the ciphertext occupy adjacent cells in one row, with one bit of the ciphertext in each cell. Align the key (the one-time pad) with the ciphertxt in the next row. Note that the key should be of the same length as the ciphertext. In the next row, enter a formula that computes the plaintext (message). .LocalAreaNetwork(LAN)isoneofthebasictypesofcomputernetworks.Briefly describeaboutlocalareanetworkincludingthemajortypesandfeaturesofLAN.Why is it that hashing passwords rather than encrypting the password file is a much better idea when putting them in a file?
