+In computer science, a **stack** is an abstract data type that serves
 as a collection of elements, with two principal operations:
 
 * **push**, which adds an element to the collection, and
 * **pop**, which removes the most recently added element that was not yet removed.
 
-The order in which elements come off a stack gives rise to its 
-alternative name, LIFO (last in, first out). Additionally, a 
-peek operation may give access to the top without modifying 
-the stack. The name "stack" for this type of structure comes
