If w is a string of english letters a–z (all uppercase for the purposes of this problem), let wr denote the reverse of w; (train)r=niart. a palindrome is a string that is its own reversal: w = wr. for example, bzrzb is a palindrome of length 5. we are not concerned with whether it is an actual english word. find a formula for the number of palindromes of length k. you will need to treat odd (k = 2m + 1) and even (k = 2m) lengths differently
