Use a start pointer and an end In this approach, we will loop through characters of input string s and capture character and its count into a HashMap and when the HashMap size reached k, keep track of the longest length Practice this problem. I am also aware that this problem can be solved without using recursion. Example: Input: String="araaci", K=2 Output: 4 Explanation: The longest substring with no more than '2' distinct characters is "araa". Examples: Input: str = "baaabbabbb" Output: 7 "aabbabb" is the required substring. You can choose any character of the string and change it to any other uppercase English character. The first occuring longest 0-interspace substring is dd. Base Case: If the string length is less than k, no substring can meet the condition, so return 0. if there are multiple substrings of the longest length, return the one that occurs first in word.
