Method 1 (Brute Force) If the length of string is n, then there can be n* (n+1)/2 possible substrings. A simple way is to generate all the substring and check each one whether it has exactly k unique characters or not. If we apply this brute force, it would take O (n 2) to generate all substrings and O (n) to do a check on each one.
WebApr 10, 2024 · If the substring the start in low and ends in high is balanced, move low and high to AFTER the substring, again with an high being one more than low. If it's not balanced, just increase high. And in case high is going out of the bounds of the string, increase low, and again make high one more than low.
