Manacher's Algorithm is an efficient method used to find the longest palindromic substring in a given string in linear time, specifically . This algorithm cleverly avoids redundant checks by maintaining an array that records the radius of palindromes centered at each position. It utilizes the concept of symmetry in palindromes, allowing it to expand potential palindromic centers only when necessary.
The key steps involved in the algorithm include:
#
) between each character and at the ends.By the end of the algorithm, the longest palindromic substring can be easily identified from the original string, making it a powerful tool for string analysis.
