What is Stack? Explain its uses.Stack is a collection of objects that works in LIFO (Last in First out) mechanism. This means that the object that is inserted first is removed last in a stack. Stacks are used in expression evaluations and syntax parsing. Expressions are evaluated from L to R and stacks can be implemented to evaluate them using “Push” and “pop”.
