Student S3 begins with the third locker and changes every third locker (closes it if it was open, and opens it if it was closed). Student S4 begins with locker L4 and changes every fourth locker. Student S5 starts with L5 and changes every fifth locker, and so on, until student S100 changes L100 After all the students, have passed through the building and changed the lockers which lockers are open? Write a program to find your answer. (Hint: Use an array of 100 boolean elements, each of which indicates whether a locker is open (true) or closed (false). Initially, all lockers are closed.) The program should display the answer like this: Sample Output: Locker x is open Locker y is open Locker z is open Coding: Name your program LockerPuzzle.java Program 2: (Pattern Recognition)Consecutive four equal numbers Problem Description: Write the following function that tests whether a two-dimensional list has four consecutive numbers of the same value, either horizontally, vertically, or diagonally ublic static va Write a test program that prompts the user to enter the number of rows and columns of a two-dimensional list and then the values in the list and displays True if the list contains four consecutive numbers with the same value.
