Distinct Substring length

Instructions

Create a class DistinctSubstringLength that provides a method to find the length of the longest substring without repeating characters in a given string.

The distinction between characters should be case-sensitive.

Expected Class

public class DistinctSubstringLength {
    public int maxLength(String s) {
        // Implementation to find the length of the longest substring without repeating characters
    }
}

Usage

Here is a possible ExerciseRunner.java to test your class:

public class ExerciseRunner {
    public static void main(String[] args) {
        DistinctSubstringLength finder = new DistinctSubstringLength();

        // Test cases
        System.out.println(finder.maxLength("abcabcbb")); // Expected output: 3
        System.out.println(finder.maxLength("bbbbb")); // Expected output: 1
        System.out.println(finder.maxLength("pwwkew")); // Expected output: 3
        System.out.println(finder.maxLength("")); // Expected output: 0
    }
}

Expected Output

$ java -cp build ExerciseRunner
