Anti Palindrome

**Definitions:** A string $T$ is called **semi-palindrome** if you can rearrange the characters of $T$ to make it into a [palindrome](https://en.wikipedia.org/wiki/Palindrome).\ For eg. if $T = aabb$, it isn't a palindrome as of now, but it can be rearranged to form $abba$, which is a palindrome. Thus, $T = aabb$ is a semi-palindrome. An **anti-palindrome** is the opposite of a semi-palindrome.
