Question
Consider the following operation performed on a stack of size 5.Push(1);Pop();Push(2);Push(3);Pop();Push(4);Pop();Pop();Push(5);After the completion of all operation, the number of elements present in stack is?
Solution
Let's go through the operations one by one:
-
Push(1): This operation adds the element '1' to the stack. The stack now contains one element.
-
Pop(): This operation removes the top element from the stack. Since we only had one element ('1'), the stack is now empty.
-
Push(2): This operation adds the element '2' to the stack. The stack now contains one element.
-
Push(3): This operation adds the element '3' to the stack. The stack now contains two elements.
-
Pop(): This operation removes the top element from the stack. The element '3' is removed, leaving the stack with one element ('2').
-
Push(4): This operation adds the element '4' to the stack. The stack now contains two elements.
-
Pop(): This operation removes the top element from the stack. The element '4' is removed, leaving the stack with one element ('2').
-
Pop(): This operation removes the top element from the stack. The element '2' is removed, leaving the stack empty.
-
Push(5): This operation adds the element '5' to the stack. The stack now contains one element.
So, after the completion of all operations, the number of elements present in the stack is 1.
