Complexity Analysis: Time Complexity: O(n 2); Auxiliary Space: O(n) Space Optimization using Trie Data Structure (when we just need count of distinct substrings). We can use a HashMap to remember the frequency of each character we have processed. I am passing the test cases, but getting TLE when I submit. Then T test cases follow. Naive Approach: The simplest approach to solve the given problem is to generate all substrings of the given string and count those substrings that have at least K distinct characters in them. Given a string S with only lowercase characters. LintCode/LeetCode Summary. Ana 21212 2. Instead of asking for unique substrings count in whole string S, query q containing indexing ( i, j) where 0 i j < n is asking for count of distinct substring inside given query range for string S [ i.. j]. skinny syrup salted caramel review accenture test pattern 2022. 7 I was solving DISTINCT SUBSTRING (given a string, we need to find the total number of its distinct substrings). 1698.

The above approaches makes use of hashing which may lead to memory limit exceeded (MLE) in case of very large strings. Then create a set of palindromes (e.g. So if you count i | S [ i] |, you will get all the substrings, but of course you overcount the number of different substrings.
