Explanation:

Read a string from user and assign it to variable "s".Call the method isPalindrome() with parameter "s".In this function find the length of the string.Then compare first  character with last and second with second last and so on.If the string is palindrome then it will return 1 else it will return 0.

Output:

Enter a string:rotor                                                                                                      

Given String is a palindrome

definition of done. the definition of done may be changed at any time to reflect what a team can complete within each sprint. however, changing the dod should be an infrequent occurrence, and never something done prior to each sprint.
