Question
Select the correct answerFollowing sequence of operations is performed on a stack push(6),push(7),pop, push(5),push(4)pop,pop,pop,push(3),pop.The sequence of poped out values areOptions7,4,5,6,37,4,5,3,67,5,4,6,33,4,5,6,7
Solution
The sequence of operations performed on the stack are as follows:
- push(6): The stack now contains 6.
- push(7): The stack now contains 7, 6.
- pop: The operation removes 7 from the stack. The popped value is 7.
- push(5): The stack now contains 5, 6.
- push(4): The stack now contains 4, 5, 6.
- pop: The operation removes 4 from the stack. The popped value is 4.
- pop: The operation removes 5 from the stack. The popped value is 5.
- pop: The operation removes 6 from the stack. The popped value is 6.
- push(3): The stack now contains 3.
- pop: The operation removes 3 from the stack. The popped value is 3.
So, the sequence of popped out values are 7, 4, 5, 6, 3. Therefore, the correct answer is "7,4,5,6,3".
