LeetCode ProblemSliding Subarray Beauty
Given an integer array nums containing n integers, find the beauty of each subarray of size k. The beauty of a subarray is the xth smallest integer in the subarray if it is negative, or 0 if there are fewer than x negative integers. Return an integer array containing n - k + 1 integers, which denote the beauty of the subarrays in order from the first index in the array.
