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.
A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:
\n\n\nInput: nums = [1,-1,-3,-2,3], k = 3, x = 2\nOutput: [-1,-2,-2]\nExplanation: There are 3 subarrays with size k = 3. \nThe first subarray is\n\n[1, -1, -3]and the 2nd smallest negative integer is -1. \nThe second subarray is[-1, -3, -2]and the 2nd smallest negative integer is -2. \nThe third subarray is[-3, -2, 3]and the 2nd smallest negative integer is -2.
Example 2:
\n\n\nInput: nums = [-1,-2,-3,-4,-5], k = 2, x = 2\nOutput: [-1,-2,-3,-4]\nExplanation: There are 4 subarrays with size k = 2.\nFor\n\n[-1, -2], the 2nd smallest negative integer is -1.\nFor[-2, -3], the 2nd smallest negative integer is -2.\nFor[-3, -4], the 2nd smallest negative integer is -3.\nFor[-4, -5], the 2nd smallest negative integer is -4.
Example 3:
\n\n\nInput: nums = [-3,1,2,-3,0,-3], k = 2, x = 1\nOutput: [-3,0,-3,-3,-3]\nExplanation: There are 5 subarrays with size k = 2.\nFor\n\n[-3, 1], the 1st smallest negative integer is -3.\nFor[1, 2], there is no negative integer so the beauty is 0.\nFor[2, -3], the 1st smallest negative integer is -3.\nFor[-3, 0], the 1st smallest negative integer is -3.\nFor[0, -3], the 1st smallest negative integer is -3.
