In this video, we solve the "Optimal String Repetition" problem: Finding the minimum number of times String A must be repeated so that String B becomes a substring of it.

This is a common coding interview question that tests your understanding of string manipulation, edge cases, and efficient search algorithms. We break down the logic, analyze the mathematical boundaries for the repetitions, and implement a clean solution in Python.

🚀 What we cover:

Logical breakdown of the repeating string pattern.

Identifying the lower and upper bounds for repetitions.

Efficiently checking for substrings.

Complexity analysis (Time & Space).
