Solution
A stack in computer science is a data structure that follows the Last-In-First-Out (LIFO) principle. This means that the last element that was added to the stack will be the first one to be removed.
Given that the elements "A", "B", "C", and "D" are placed in a stack, they would be placed in this order:
Top -> D C B A Bottom
When we start removing the elements one at a time from the top of the stack, the order of removal will be "D", "C", "B", "A". This is because "D" was the last element placed on the stack, so it will be the first one to be removed, followed by "C", then "B", and finally "A".
