We can find the longest palindrome substring ( LPS ) in (n^2) time with O (1) extra space. The algorithm below is very simple and easy to understand. The idea is to Fix a center and expand in both directions for longer …

Web9 feb. 2024 · The idea behind Manacher's algorithm is to find the length of the longest palindrome centered at each character in the input. To do this, the algorithm uses two array: one to keep track of the length of the longest palindrome centered at each character and another to keep track of the center of the longest palindrome that includes that …

Manacher algorithm uses palindrom's property that it is symmetric around center. Finding center is relatively straight forward for odd length strings. Adding characters to even length string ensures string becomes of odd length. So, if your string is even length then it is necessary to add characters. Share.
Web6 mei 2012 · Manacher's algorithm fills in a table P[i] which contains how far the palindrome centered at i extends. If P[5]=3, then three characters on either side of position five are part of the palindrome. The algorithm takes advantage of the fact that if you've found a long palindrome, ...
