2653 - Sliding Subarray Beauty.

Medium

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:

Input: nums = [1,-1,-3,-2,3], k = 3, x = 2

Output: [-1,-2,-2]

Explanation: There are 3 subarrays with size k = 3.

The first subarray is [1, -1, -3] and the 2^nd smallest negative integer is -1.

The second subarray is [-1, -3, -2] and the 2^nd smallest negative integer is -2.

The third subarray is [-3, -2, 3]and the 2^nd smallest negative integer is -2.

Example 2:

Input: nums = [-1,-2,-3,-4,-5], k = 2, x = 2

Output: [-1,-2,-3,-4]

Explanation: There are 4 subarrays with size k = 2.

For [-1, -2], the 2^nd smallest negative integer is -1.

For [-2, -3], the 2^nd smallest negative integer is -2.

For [-3, -4], the 2^nd smallest negative integer is -3.

For [-4, -5], the 2^nd smallest negative integer is -4.

Example 3:

Input: nums = [-3,1,2,-3,0,-3], k = 2, x = 1

Output: [-3,0,-3,-3,-3]

Explanation: There are 5 subarrays with size k = 2**.**

For [-3, 1], the 1^st smallest negative integer is -3.

For [1, 2], there is no negative integer so the beauty is 0.

For [2, -3], the 1^st smallest negative integer is -3.

For [-3, 0], the 1^st smallest negative integer is -3.

For [0, -3], the 1^st smallest negative integer is -3.

Constraints:

• n == nums.length
• 1 <= n <= 105
• 1 <= k <= n
• 1 <= x <= k
• -50 <= nums[i] <= 50
