WitrynaPractice this problem. A simple solution would be to generate all substrings of the given string and return the longest substring containing k distinct characters. The time complexity of this solution is O(n 3) since it takes O(n 2) time to generate all substrings for a string of length n and O(n) time to process each substring..

Witryna14 lut 2024 · If yes then compare the length of this substring with the minimum length substring found earlier. Generate all the substring. Check if the current substring contains exactly k distinct characters. Minimize the length of such valid substring and keep it into result. Finally, return the result. Witryna15 lut 2024 · Number of distinct substrings . Every substring is a prefix of some suffix. A suffix of length q has q prefixes. But if we would simply sum up the length of every suffix, then we might count some substrings several times. The key idea is that we assign each substring to the lexicographical smallest suffix for which it is a prefix. martin luther king jr time travel movieWitrynaThe SQL SELECT DISTINCT Statement. The SELECT DISTINCT statement is used to return only distinct (different) values.
