## Overview

This is a small Python script that computes the longest sequence of distinct alphabetic characters under its reset rules. Its entry point calls the function with a hardcoded sample and prints the result; it does not read user input. The function resets its current sequence on nonletters or repeated characters. The graph reflects the single provided source file.

Main entry points: [`main.py`](https://github.com/m-saad-k/hackerrank-max-unique-substring-length-in-a-session/blob/main/main.py) (Script entry)
