A palindrome is a symmetric, mirror image string such as "otto" or "kayak." How would you search for a palindrome pattern P in a string text T?

a. Search for the prefix and suffix
b. Use the naïve string match algorithm
c. Use the Boyer-Moore string match algorithm
d. A string match for a palindrome is not possible


a. Search for the prefix and suffix
Search for the prefix of the palindrome, half the string "ot"; and then search for the suffix of a palindrome, the reverse of the string, which is "to", after each match of the prefix. For a non-even string, search for the first leading characters as the prefix "ka", then compare the single character "y", and then the suffix, the reverse of the string, which is "ak", after each match of the prefix and single character.
