Understanding the The Number of Beautiful Subsets Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an array nums of positive integers and a positive integer k. A subset of nums is beautiful if it does not contain two integers with an absolute difference equal to k. Return the number of non-empty beautiful subsets of the array nums. A subset of nums is an array that can be obtained by deleting some (possibly none) elements from nums. Two subsets are different if and only if the chosen indices to delete are different.

Get real-time assistance for The Number of Beautiful Subsets problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums = [2,4,6], k = 24The beautiful subsets of the array nums are: [2], [4], [6], [2, 6]. It can be proved that there are only 4 beautiful subsets in the array [2,4,6].
nums = [1], k = 11The beautiful subset of the array nums is [1]. It can be proved that there is only 1 beautiful subset in the array [1].
Constraints
1 <= nums.length <= 181 <= nums[i], k <= 1000How Interview Coder Helps with Leetcode Problems
