Additionally, the tree can be used to compute how many distinct palindromic substrings are in a string (it's just the number of nodes in the tree) and how frequently each such palindrome occurs. But length of the string is 13 so i<=s.length means i<=13 loop runs 14 times and the substring indexes are also out of bounds due to k+i.So if we subtract k=3 from length i.e i<=s.length-k(3) then i<=10 now the loop runs 11 times as we need and index values of substring … Both solutions did compute the same total number of unique substrings though.
