"abacb"

The longest substring without repeating characters is "acb" with a length of 3.

You do not need to print anything. The function should be implemented to return the answer.

Accepted Answer

The problem asks to find the length of the longest substring without repeating characters in a given string.

Use a sliding window approach to iterate through the string and keep track of the characters seen so far.
Maintain a set to check for duplicate characters within the current substring.
Update the maximum length of the substring whenever a duplicate character is encountered.
Continue the process until the end of the string is reached.
Return the maximum length of the substring without repeating characters.
