Improve Stack array based algorithms

[JoaoVictor6]

I propose to refactor Stack ArrayBasedStack. I was reading some C# algorithms and not understand the reason for use a iteration in line 48 of ArrayBasedStack.cs . I believe this syntax is more readable:

public ArrayBasedStack(T[] items)
{
    stack = items;
    top = items.Length - 1;
}

If this refactoring makes sense, I can make this change :)

The proposed change seems correct, could you make a PR with it and a test to check that it works?
