Question 2 (1 point) Consider the following Scala function definitions: def f [X, Y] (a:Option[X], g:X=>Y) : Option[Y] = { a match { case None => None case Some (x) => Some (g (x)) } } def index [X] (xs:List[X], n:Int) : Option[X] = { xs match { case Nil => None case y::ys if (n == 0) => Some (y) case _::ys => index (ys, n - 1) } } What is the output of running: f (index (List (10, 11, 12), 1), (n:Int) => n * 2)

In this lab, you add a loop and the statements that make up the loop body to a c++ program that is provided. when completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. your loop should execute until the user enters the character x instead of l for left-handed or r for right-handed. the inputs for this program are as follows: r, r, r, l, l, l, r, l, r, r, l, x variables have been declared for you, and the input and output statements have been written.

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.
