a. Definition P [i] represents the position of the longest may extend from both sides of the i-th position, such that i is in the center, left and right sub-extension P [i] satisfies a palindromic sequence length
a. Definition of p'i' indicates the longest position that can be extended from the i position to both sides, so that the substrings that extend the p'i's length at the i center meet the reply
A. Definition P [i] denotes the longest position that can extend from the first position to both sides, so that the substrings of left and right extended P [i] lengths satisfy palindromes with I as the center<br>
