The Lab procedures: The following files must be distributed to the students in the Lab - arrayimpOfstack.java // it represents an array implementation of the stack. - pointerimOfStack.java // it represents a Linked List implementation of the stack. - pointerImOfqueue.java // it represents a pointer implementation of the queue. Then the students by themselves are required to write the code for the following questions Ex1) Given the file arrayImpOfStack.java then write a main method to read a sequence of numbers and using the stack operation print them in reverse order. Ex2) Given the file pointerImOfStack.java then write a main method to read a decimal number and print its equivalent binary number. Ex3) Given the file arrayimpOfStack.java then write a main method: - declaring two stack objects S1, S2; - reads a sequence of numbers; store the even ones in the stack S1, and store the odd ones in the stack S2. - print the even numbers followed by odd ones. Ex4) Given the file pointerimOfQueue.java then write a main method: to - add some elements into the queue, - reverse the queue contents, (Hint use an array) - print the queue contents. Note that Ex4) can be Solved using a stack instead of the array
