Solution: Super Ugly Number

Explore how to solve the super ugly number problem by applying a k-way merge algorithm combined with a min heap. Understand the step-by-step method to generate numbers with only specified prime factors and efficiently manage duplicates, preparing you for related coding challenges.

We'll cover the following...

Statement

Given an integer n and an array of distinct prime numbers primes, return the n-th super ugly number. A super ugly number is a positive integer whose only prime factors are from a given array primes.

The n-th super ugly number is guaranteed to fit within a 32-bit signed integer.

Constraints:

  • 1≤1 \leq n ≤105\leq 10^5 ...
