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?
A.
2
B.
3
C.
6
D.
7
Correct answer is C. 6
The first pop, pops the 8, leaving 6 top of the stack.
The following Push-Pop and Pushx3-Popx3 results in no net effect so 6 is still on top.

6 is the Right answer…
Stack i = new Stack();
i.Push(2);
i.Push(4);
i.Push(6);
i.Push(8);
i.Pop();
i.Push(3);
i.Pop();
i.Push(4);
i.Push(6);
i.Push(7);
i.Pop();
i.Pop();
i.Pop();
foreach(var item in i){
Console.WriteLine(“{0} “, item);
}
