If you want to use this tool please follow this Usage Guide. If the length of string is n, then there can be n*(n+1)/2 possible substrings. The number of substrings of s is then the number of prefixes of strings in the trie, which you can calculate simply in linear time. Also, the space consumed is very large, at 4093M. You are given a string s, a split is called good if you can split s into 2 non-empty strings p and q where its concatenation is equal to s and the number of distinct letters in p and q are the same. Given a string, I know how to find the number of palindromic substrings in linear time using Manacher's algorithm. Now, this might lead to an O(n + n^2) algorithm - one 'n' for finding all such substrings, and n^2 for comparing each of these substrings with the ones already found, to check if it is … 4 0 Add to List Share.

Create a 2D array mat[m+1][n+1] where m is length of string T and n is length of string S. mat[i][j] denotes the number of distinct subsequence of substring S(1..i) and substring T(1..j) so mat[m][n] contains our solution. Given a string s, return the number of distinct substrings of s. A substring of a string is obtained by deleting any number of characters (possibly zero) from the front of the string and any number (possibly zero) from the back of the string … Initialize the first column with all 0s.
