WebAlgorithm analysis We represent a string of length n as the concatenation of two non-empty palindromes of lengths l and n – l. In the palindrome of length l, the first (l + 1) / 2 letters can be chosen arbitrarily (any of the k letters available), and the remaining letters should be chosen to obtain a palindrome. This can be done in k(l+1)/2 ways.
