A. Starting with an initially empty stack, after 6 push operations, 3 pop operations, and 2 push operations, the number of elements in the stack would be:
B. Starting with an initially empty queue, after 5 enqueue operations, 4 dequeue operations, and 6 enqueue operations, the number of elements in the queue would be:
Homework Answers
A)
Initially stack is empty, after 6 push operations there will be total of 6 elements present in the stack
after 3 pop operations 3 elements will be removed from stack so 3 elements are remaining in the stack
and 2 push operations so 2 will be pushed into stack so total of 2+3=5 elements will be present in stack
B)
Initially queue is empty, after 5 enqueue operations there will be total of 5 elements present in the queue
after 4 dequeue operations 4 elements will be removed from queue so 1 element is remaining in the queue
and 6 enqueue operations so 6 will be inserted into queue so total of 6+1=7 elements will be present in queue

Please write a Java interface for an integer stack (should have the methods push, pop, toString). Then implement this interface using one of our linked list nodes. Then please write an interface for an integer queue ( should have methods enqueue, dequeue, and toString). Then implement this interface using one of our linked list objects. Please see chapter 3 in the text for a definition of a stack. Please write a program that asks the user for how many numbers...
