WebDec 15, 2024 · So here the longest palinfromic substring length is 5. To solve this, we will follow these steps −. s2 := concatenate s twice. max_len := 0. for x in range 0 to size of s − 1, do. for y in range 0 to size of s, do. temp := s2 [from index x to x + y] if temp is palindrome and size of temp > max_len, then. max_len := size of temp. WebFeb 9, 2024 · The length of the longest palindromic substring is simply the maximum value in the P array. The P array stores the length of the longest palindromic substring centered at each character of the processed string. From the P array, we can see that the length of the longest palindromic substring is 3, which is centered at index 7.
