I dont understand this also i have 18 points im asking more questions under this

Marshmallow → Android 6

Jelly Bean → 4.1

Donut Android → 1.6

KitKat → 4.4

Honeycomb → 3.0

Gingerbread → 2.3

Explanation:

Android Marshmallow is Android's 13th version and the the 6th major version of the Android released officially on October 2015

Android Jelly Bean is the 10th version of the Android mobile operating system initially released on the 9th of July, 2012

Android Donut is the 4th version of the Android which is no longer supported and was initially released on the 15th September, 2009

Android KitKat is the 11th version of the Android that came with improved system performance and was initially released on the 31st of October 2013

Android Honeycomb is the 8th version of the Android made for devices with large screen and was initially released on the 22nd of February 2011

Android Gingerbread is the 7th version of the Android released in December 2010.

The function in Python is as follows:

def check_palindrome(strn):

   retstr = "Bummer. Not a palindrome."

   if strn[len(strn)::-1] ==strn:

       retstr = "Hey! That's a palindrome!"

   return retstr

Explanation:

This defines the function

def check_palindrome(strn):

This sets the return string to not a palindrome

   retstr = "Bummer. Not a palindrome."

This checks if the original string and the reversed string are the same

   if strn[len(strn)::-1] ==strn:

If yes, the return string is set to palindrome

       retstr = "Hey! That's a palindrome!"

This returns the expected string

   return retstr

The function to reverse the string is not given; and the programming language. So, I solve the question without considering any function
