Stack Data Structure

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?

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
