Consider the following algorithm Algorithm Mystery(A[0..n-1, 0..n - 1]) //Input: A matrix A[0..n-1, 0..n - 1] of real numbers for i ←0 to n - 2 do for ji+ 1 to n - 1 do if A[i, j] = A[j,i] return true return false a. What does this algorithm compute? b. What is its input size? c. What is its basic operation? d. How many times is the basic operation executed? e. What is the efficiency class of this algorithm? f. Suggest an improvement, or a better algorithm altogether, and indicate its efficiency class. If you cannot do it, try to prove that, in fact, it cannot be done.

In preparation for the opening of the border, the Government of Malaysia plans to develop an Electronic COVID-19 passport information system (eCPIS) to store Malaysian immunization information. You are required to develop this system to keep immunization information and allow passport control officers to retrieve each individual immunization information. eCPIS should contain the following information:Personal information (Name, passport no., age, and gender)Vaccination status (completed 2 doses or partially completed or not taken)Vaccine information (Type of vaccine, Date of receiving vaccine)PROGRAM DESIGN REQUIREMENTS: Design object-oriented programming which demonstrates the use of base class, derived class,inheritance, composition, and friend functions. The program should allow a user to do the following tasks:Enter informationUpdate vaccination information.Search each individual vaccination information status via passport no.list of unvaccinated personslist of individuals who…
