What is the value of the median-of-3 for the following list. [80, 47, 41, 21, 40, 68, 78, 18, 75, 46, 30] Notes: • Your answer should be a single valid, non-negative, literal Python int value. For example, 123 is a valid int literal. • This question is asking about before any partition operation is carried out. • This is not asking for the median-of-3 index. • You can pre-check your answer (to check it's a valid, non-negative, literal int).

You are required to propose FOUR functions to develop a complete student record management system. The function are insert, delete, search, update. In addition, you need to use sorted array to complete the system development. Write a program by extending the code from the lab. Think and implement 4 more functions in the program (compulsory function is sorting and searching) Your must build on top of the following code. //FileName: Student.cpp //This program illustrates attributes of class Student using simple data structure #include <iostream.h> class Student { private: struct Data { char Name[25]; char Course[30]; int Result; } stdata; public: void SetData(); void GetData(); };//class Student void Student::SetData() { cout <<”Enter student name:”; cin>> stdata.Name; cout<< “Enter student course: “; cin>> stdata.Course; cout<< “Enter student result:”; cin>> stdata.Result; };//method SetData void Student::GetData() { cout<< “\n…

Problem 2: Create a ticket spin lock Complete the functions in ticket_spin_lock.cpp to implement a ticket lock that spins while waiting. Some useful hints: • The lock_t* lock struct containts the variables int ticket and int turn. • Use the atomic function_sync_fetch_and_add( int* ticket, int addition ). This function will atomically fetch the value in ticket and add addition to this value. • You may not need to do anything in the destroy function.

Which of the following statements about static and dynamic library is/are INCORRECT? (a) libTeslaFactory.a used in Assignment 2 is a static library. (b) Static libraries use more memory as they copy code into executable files. (c) One advantage of static libraries is that they are directly executable. (d) Calling shared libraries functions won't generate page faults as they are usually resident in memory. (e) None of the above (i.e., (1)-(4) are all CORRECT)
What is the index of the median-of-3 for the following list. [39, 27, 67, 91, 24, 28, 17, 70, 12, 89, 16, 69] Notes: • Your answer should be a single valid, non-negative, literal Python int value. For example, 123 is a valid int literal. • This question is asking about before any partition operation is carried out. • This is not asking for the median-of-3 value. • You can pre-check your answer (to check it's a valid, non-negative, literal int).
