Objective: Given two string sequences write an algorithm to find, find the length of longest substring present in both of them. So at any point of time, the sliding window would contain a substring of first string of size m. At each iteration of the loop, we remove leftmost element from the sliding window and add next character of first string to it so it points to next substring of X. Let S[i] denote the set of all unique substrings of the string w[i]. 1 4: The substrings of abaa are a, b, ab, ba, aa, aba, baa, and abaa, so we print on a new line. Any ordered substring must be contained in one of these runs, This allows you to just iterate once through the string O(n). It only takes a minute to sign up. I have this code that I found on another topic, but it sorts the substring by contiguous characters and not by alphabetical order. I could solve this in 10 minutes but I am not sure if this is a very efficient code. Method 1 (Brute Force) If the length of string is n, then there can be n*(n+1)/2 possible substrings.
