You are given a 0-indexed integer array nums and an integer x.
Find the minimum absolute difference between two elements in the array that are at least x indices apart.
In other words, find two indices i and j such that abs(i - j) >= x and abs(nums[i] - nums[j]) is minimized.
Return an integer denoting the minimum absolute difference between two elements that are at least x indices apart.
Examples
Example 1
Input: nums = [4,3,2,4], x = 2
Output: 0
Explanation: We can select nums[0] = 4 and nums[3] = 4.
They are at least 2 indices apart, and their absolute difference is the minimum, 0.
It can be shown that 0 is the optimal answer.
Example 2
Input: nums = [5,3,2,10,15], x = 1
Output: 1
Explanation: We can select nums[1] = 3 and nums[2] = 2.
They are at least 1 index apart, and their absolute difference is the minimum, 1.
It can be shown that 1 is the optimal answer.
Example 3
Input: nums = [1,2,3,4], x = 3
Output: 3
Explanation: We can select nums[0] = 1 and nums[3] = 4.
They are at least 3 indices apart, and their absolute difference is the minimum, 3.
It can be shown that 3 is the optimal answer.
Constraints
1 <= nums.length <= 105
1 <= nums[i] <= 109
0 <= x < nums.length
