A palindrome is a word that may be read the same way in either direction. Accept a sentence in UPPER CASE which is terminated by either ".", "?", or "!". Each word of the sentence is separated by a single blank space.
Perform the following taks:

(a) display the count of palindromic words in the sentence.
(b) Display the palindromic words in the sentence.

Example of palindromic words:

MADAM, ARORA, NOON

Test your program with the sample data and some random data:

Example 1
INPUT : MOM AND DAD ARE COMING AT NOON
OUTPUT : MOM DAD NOON
NUMBER OF PALINDROMIC WORDS : 3


Example 2

INPUT : HOW ARE YOU?
OUTPUT : NO PALINDROMIC WORDS
