2. Suppose an Array based global Stack is implemented with a given maxSize. User is going to give a “lucky_number". Write a method 'int popNonLucky(int lucky_number)' which is going to pop all numbers except luck number. Finally, the Stack needs to be compact so that only luck_number present(s) in Stack. And the method should return total lucky_numbers found.

2. Suppose an Array based global Stack is implemented with a given maxSize. User is
going to give a "lucky_number". Write a method 'int popNonLucky(int lucky_number)'
which is going to pop all numbers except luck_number. Finally, the Stack needs to be
compact so that only luck_number present(s) in Stack. And the method should return
total lucky_numbers found.
