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.
\n\t\n
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.
