Solution: Nth Magical Number
Understand how to calculate the nth magical number divisible by either of two given integers efficiently. Explore the use of binary search combined with the inclusion-exclusion principle to count multiples and handle large constraints. This lesson helps you implement a solution that returns the result modulo 10^9+7 while analyzing time and space complexity.

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
