Solution: Super Ugly Number

Explore how to find the nth super ugly number using a k-way merge approach combined with a min heap. Understand how to dynamically generate these numbers in increasing order without redundancy, and implement this efficient solution to solve problems involving prime factor multiples.

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

  • 1≤1 \leq primes.length ...
