Write a program to implement problem statement below; provide the menu for input N and number of experiment M to calculate average time on M runs. randomly generated list. State your estimate on the BigO number of your algorithm/program logic. (we discussed in the class) Measure the performance of your program by given different N with randomly generated list with multiple experiment of Ns against time to draw the BigO graph (using excel) we discussed during the lecture.

Which of the following is true? a. There are RFCs that describe challenge-response authentication techniques to use with email. b. Filtering for spam sometimes produces a false positive, in which legitimate email is identified as spam. c. Spam relies heavily on the absence of email authentication. d. All of the above.
The option that is true is option b. Filtering for spam sometimes produces a false positive, in which legitimate email is identified as spam.
How is spam filtration carried out?The processing of email to organize it in accordance with predetermined criteria is known as email filtering. The word can allude to the use of human intelligence, although it most frequently describes how messages are processed automatically at SMTP servers, sometimes using anti-spam tactics.
Therefore, Email filtering operates as previously stated by scanning incoming messages for red flags that indicate spam or phishing content and then automatically transferring such messages to a different folder. Spam filters evaluate an incoming email using a variety of criteria.
