Thinking-Bear gave a string of letters to the sister who admired in the heart. Sister looked at the string and said to Thinking-Bear: “I hope it is symmetrical”. Thinking-Bear decided to cut a continuous part from the original string and join to form a new necklace. A necklace is symmetrical if we can cut it into a palindrome.

Thinking-Bear can use magic. He can replace one letter to another letters. The magic can be used at most twice. Thinking-Bear want to know what’s the longest length of necklace he is able to capture. We assume that the length of the new necklace must be an odd number.
