LISP programming structure is composed of symbolic expressions or s-expressions. The s-expression consists of three valid objects
• Atom: It is a number or string of contiguous characters
• Lists : A list is a sequence of atoms or other lists enclosed in parentheses
• String: A group of characters enclosed in double quotation marks is referred as String.
LISP programs can be either run on an interpreter or as a compiled code
