    All characters except the middle one are the same, e.g. aadaa. A special substring is any substring of a string which meets one of those criteria. Given a string, determine how many special substrings can be formed from it. For example, given the string s= mnonopoo, we have the following special substrings: {m, n, o, n, o, p, o, o, non, ono. In this approach, the corner case of the empty string is checked for. The list is not sorted and the first element in the list is initially assumed to be the longest prefix. Every word's length is compared to the assumed prefix's length. If the length of the prefix is smaller than the string with which it is compared, the old prefix is retained. Time complexity of this solution would be O(n^3). Method 2 (Linear Time) Let us talk about the linear time solution now. This solution uses extra space to store the last indexes of already visited characters. The idea is to scan the string from left to right, keep track of the maximum length Non-Repeating Character Substring (NRCS) seen so far. Explanation. n.substring(0,8) returns the substring of n starting at index 0 till 7 (i.e. 8 - 1 = 7) which is "Computer".m.substring(9) returns the substring of m starting at index 9 till the end of the string which is "Applications". concat() method joins "Computer" and "Applications" together to give the output as ComputerApplications.
