Solution: Nth Magical Number
Understand how to determine the nth magical number divisible by either of two given integers by applying binary search combined with the inclusion-exclusion principle. Explore how to calculate the count of divisible numbers up to a value and use the least common multiple to avoid double counting. This lesson guides you through implementing an optimized approach with a clear time and space complexity analysis.

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
