Output: Anagram YZX present at index 2 Anagram XZY present at index 4 Anagram YZX present at index 6 Anagram XYZ present at index 9 . So if you count $\sum_i |S[i]|$, you will get all the substrings, but of course you overcount the number of different substrings. The reason it is stored like this is because the front application it pulls the data from, has check boxes for each truck, so when you check a check box next to the truck, it adds the truck name onto the string. Let's have a closer look. GeeksforGeeks 729 views. Please go through Frequently asked java interview Programs for more such programs. In this article, I am going to discuss How to Find All Substrings of a Given String in C# with some examples. It's almost 0.99995% of the maximal value we could get. Active 2 years, 2 months ago. As part of this article, we are going to implement the above program with the following ways. Example Input abcd Output 10 All Elements are Distinct Input aaa Output 6 If you are blindly adding the substrings to a storage you have, you will end up with copies of “ab”, which is not what we want. Example. Distinct Echo Substrings in C++ C++ Server Side Programming Programming Suppose we have a string S; we have to find the number of distinct non-empty substrings of S that can be written as the concatenation of some string with itself. 2. 3. if string is aa, it's distinct substrings are a and aa. You are given a string consisting of n lowercase Latin letters. Input Format. Sample Input: 2 CCCCC ABABA. In this method, we first calculate all the possible substring by using nested for loops. If the current character is a new character for this substring, then increament distinct_count. Then follows description of test cases. Please read our previous article where we discussed how to remove duplicate characters from a string in C# with some examples. The next T lines contains the string S. Output: Find all distinct palindromic sub-strings for a given string. This is the best place to expand your knowledge and get prepared for your next interview. Input. For example, "abbccbbadad" has 3 because "bb" is composed of 2 "b"s, "cc" is composed of 3 "c"s, and "adad" is composed of 2 "ad"s. Given a string S consisting of uppercase alphabetic characters.
