Solution: Nth Magical Number
Understand how to determine the nth magical number divisible by either a or b using efficient binary search combined with the inclusion-exclusion principle and least common multiple calculations. This lesson guides you through implementing a solution that avoids explicit sequence generation, ensures optimal time complexity, and applies modular arithmetic for large results.

Statement
Given three integers n, a, and b, return the nth magical number.
A magical number is defined as a positive integer that is divisible by either a or b.
As the result may be very large, return it modulo
