The Number of Good Subsets

Explore how to identify and count subsets of an integer array whose product is a product of distinct prime numbers. Understand the constraints on prime factors, apply dynamic programming techniques, and learn to solve this problem efficiently using memoization and modular arithmetic.

Statement

For a given integer array, nums, you can say that a subset of nums is called “good” if the product of its elements can be expressed as a product of one or more distinct prime numbers, i.e., no prime ...
