Stack Data Structure

Question

Hey guys! I got the question below from a book that I'm studying, but the answer of the book doesn't look correct for me. What the answer to the question below for you guys? Tks in advance.

You have a stack that contains integer values.
The values are pushed onto the stack in the following order: 2,4,6,8. The following sequence of operations is executed:
Pop
Push 3
Pop
Push 4
Push 6
Push 7
Pop
Pop
Pop

What is the value of the top element after these operations are executed?

Answer 1

stack is working on the principle of last in first out so it will execute like this
the sequence in the stack is 2,4,6,8
Pop
=>2,4,6
Push 3
=>2,4,6,3
Pop
=>2,4,6
Push 4
=>2,4,6,4
Push 6
=>2,4,6,4,6
Push 7
=>2,4,6,4,6,7
Pop
=>2,4,6,4,6
Pop
=>2,4,6,4
Pop
=>2,4,6

top is indicate the top most element in the stack so the value of top is 6
