#  *****************"{LIST DATA TYPE}"*********************

#--> If we want to represent a group of values as a SINGLE ENTITY where
#    INSERTION Order required to preserve and DUPLICATE are allowed then we should go for list 
#     DATATYPE.

#1) Insertion Order is Preserved.

#2)HETEROGENOUS Obejects are allowed.

#3) Duplicate are allowed.

#4) GROWABLE in Nature.

#5) Values should be enclosed within Square Brackets.

# LIST ---> It's growable in Nature i.e based on our requirement we can increase /or/
#           decrease the SIZE.
