Q.No.1:
a) Why would we use circular Queue instead of a simple or Double Ended Queue? Explain
b) Consider the Double ended output restricted Queue implemented as a circular array based queue at
the right. How will it look like after following operations have been performed on it in the given
order:

c) Palindrome is a word that reads the same backwards and forwards e.g, MADAM, POP, TAT etc.
are palindromes. Write a C++ program that checks whether a given string is a Palindrome or not
using an appropriate data structure. Enter your first name as an input to your program and add a
screen shot here which displays either its palindrome or not?
