Check Anagram Using Bit Manipulation

An Anagram is a special type of word or phrase where rearranging the letters will create a valid new word.

• The longest anagram of a single word, which uses all 27 letters is hydroxydeoxycorticosterones and hydroxydesoxycorticosterone
• Japan's former capital Kyoto and current capital Tokyo are anagrams of each other.
• The special words whose anagram are Palindromes as well, ie when read in reverse order, it creates a new word are called semordnilap. For example, stressed and desserts.
• In Harry potter book series, the main antagonist, Lord Voldemort's childhood name was Tom Marvolo Riddle which is an anagram of i am lord voldemort
• The most expendable synthetic fiber Spandex is an anagram of expands.
• The special words whose anagrams have Opposite meanings are called Antigrams For example, Santa is the word Satan.
• The anagrams of eleven plus two is twelve plus one.
