I’m needing to reverse an A stack using another additional stack B and some variables in pseudo code. For the stack A to be reversed at the end of the algorithm. Someone can help?

When stacking, the last entry becomes the first exit. Knowing this, just remove the stack elements at the same time you add it in another.
Cell A = 5, 4, 3, 2, 1 (Top)
Stack B;
Cell A = 5, 4, 3, 2 (Top)
Cell B = 1;
Cell A = 5, 4, 3 (Top)
Cell B = 1, 2;
etc..

R.Carvalho, I need to invert to A to B, but I need to invert to A so that it is reversed from A initially. That is, I need the stack A to be reversed using the B and some variables so that when it goes back to A it is totally reversed

At the end of this example, Voce will have the stack B reversed to A, now it is necessary to pass B to A using variables, to the point that A is exactly like B now, reversed.

Is battery B obligatory? Using Bubble Sort nor is it necessary to have another battery.

Yes Diego, it is mandatory to use a stack B and after reversing on stack B, use variables to return the elements to stack A.
