Solution: Super Ugly Number

Explore how to find the n-th super ugly number whose prime factors come from a given list. Learn to apply k-way merge and min heap techniques to generate numbers in order without duplicates. Understand how this approach optimizes time complexity to O(n log k) and space complexity to O(n + k).

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:

  • 11 \leq n 105\leq 10^5 ...
