"Master Number of distinct substrings in a string: Take `s` (string), execute an optimal problems strategy, and return boolean with clean edge-case handling."
Real-World Metaphor:
Think of Number of distinct substrings in a string as an everyday real-world challenge: you receive input data, inspect its elements in sequence without making unnecessary duplicate passes, and transform the collection to reach the exact target without wasting computer memory.

1. Initialize State for Number of distinct substrings in a string
Load inputs and initialize algorithmic registers.
How to Think About This (Mental Model)
Unpack the problem parameters (`s` (string)) and clarify what is given vs what must be returned.
Identify the optimal data structure or pattern (e.g. pointers, hash map, or stack) to avoid redundant recalculations.
Walk through state transitions, handle edge cases (empty collections, single items, negative numbers), and return the verified result.
Given a string `s`, implement an optimal algorithmic solution for **Number of distinct substrings in a string**.
Your solution should aim for optimal time complexity and handle all edge cases such as empty strings and character frequencies.
Examples
Example 1
Input: s = "racecar"
Output: true
Example 2
Input: s = "hello"
Output: false
Constraints
1 <= s.length <= 10^5
s consists of lowercase English letters and printable characters.
