Let A be the set containing these characters, and B be the set containing your age, last name, favorite number, and expected grade in this course. Take X= A U B. Do the following: [ Set A = {Iron Man, Scarlet Witch, Thor, Shinichi, Ran} , Set B= {21, Melgar, 14, 70}] b. Enumerate the equivalence classes induced by the equivalence relation ρ. Use the roster method in writing each class.Bus Loading Problem. You are in charge of filling busses with passengers at a bus terminal. Each bus has space for ten (10) passengers. Four (4) of those spaces can hold only wheelchair passengers, and the other six (6) can hold only non-wheelchair passengers. Busses and both types of passengers arrive at random. As busses arrive, you are to fill them up with passengers. Once a bus is full (containing 6 non-wheelchair, and 4 wheelchair passengers), it is allowed to leave the terminal, along with its passengers. You are responsible only for loading the passengers on the bus and having the bus depart. You do not need to worry about what happens to the busses or passengers after they leave. Each bus process has available to it the functions ArriveAtTerminal(), OpenDoors(), CloseDoors(), and DepartTerminal(). Each passenger process has available to it the functions ArriveAtTerminal() and GetOnBus(). Executing GetOnBus() loads the passenger on the bus, and the function returns when the…OCAML Programming language Sliding tiles The mechanics described in this exercise can be used to implement a game sliding tiles. 1. Create a type slidingTile, consisting of a char matrix and two integers x and y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in the matrix, it slides the tile from the specified location to the empty tile, then returns the altered sliding Tile. If provided location is not adjacent to the empty tile, or out of bounds, then return the slidingTile unaltered. 3.Create a function val print_tile : slidingTile -> unit = <fun> that prints a sliding Tile on screen with the corresponding characters from the matrix. However, print an empty space where the empty tile is instead.
