Python 3.7.4: Assume that C is a variable has been assigned a string value. Write an expression whose value is true if and only if C is what is called a whitespace character.

- Answer in Java Only Ranjit has always been very interested in palindromic strings. So as the word suggest palindromic string is a string which is same form both the end. Recently, he discovered something interesting on palindrome and that made him feel really lucky. He came across something known as Lucky Palindromes. Defines a character unit as a lucky palindrome if it is a palindrome containing a "lucky" character unit as a small series. As usual, he now wants to turn every thread he encounters into a lucky palindrome. As a chef, he is a patient and creative man, so he knows the task of changing any string character with any other character very well and can perform this action many times indefinitely. He wants you to write a program that will help him to turn a given series into a lucky palindrome that uses a small amount of functionality and if a few such palindromes can happen, then take out one very small dictionary.

For some mysterious reason, the Java String type does not come with a reverse method.
