Manacher's algorithm python

WebAlgorithms Boyer Moore String Search Algorithm. Boyer Moore string search algorithm is an efficient string searching algorithm which was developed by Robert S. Boyer and J Strother Moore in 1977. The time complexity is linear in terms of length of data to be searched and preprocessing complexity is linear as well. Piyush Mittal WebManacher's algorithm is faster because it reuses precomputed data when a palindrome exists inside another palindrome. There are 3 cases of this. They are represented by the …
