WebManacher's algorithm is used to find longest palindromic substring in linear time complexity. Piyush Mittal Intern at OpenGenus and WordPlay B. Tech in Computer Science at Institute of Engineering & Technology Read More Improved & … In computer science, the longest palindromic substring or longest symmetric factor problem is the problem of finding a maximum-length contiguous substring of a given string that is also a palindrome. For example, the longest palindromic substring of "bananas" is "anana". The longest palindromic substring is not guaranteed to be unique; for example, in the string "abracadabra", there is no palindromic substring with length greater than three, but there are two palindromic s…

WebFor almost twenty years, the Ford-Johnson algorithm for sortingt items using comparisons was believed to be optimal. Recently, Manacher was able to show that the Ford-Johnson algorithm is not optimal for certain ranges of values oft.
