2905. Find Indices With Index and Value Difference II
Description
You are given a 0-indexed integer array nums
having length n
, an integer indexDifference
, and an integer valueDifference
.
Your task is to find two indices i
and j
, both in the range [0, n - 1]
, that satisfy the following conditions:
abs(i - j) >= indexDifference
, andabs(nums[i] - nums[j]) >= valueDifference
Return an integer array answer
, where answer = [i, j]
if there are two such indices, and answer = [-1, -1]
otherwise. If there are multiple choices for the two indices, return any of them.
Note: i
and j
may be equal.
Example 1:
Input: nums = [5,1,4,1], indexDifference = 2, valueDifference = 4 Output: [0,3] Explanation: In this example, i = 0 and j = 3 can be selected. abs(0 - 3) >= 2 and abs(nums[0] - nums[3]) >= 4. Hence, a valid answer is [0,3]. [3,0] is also a valid answer.
Example 2:
Input: nums = [2,1], indexDifference = 0, valueDifference = 0 Output: [0,0] Explanation: In this example, i = 0 and j = 0 can be selected. abs(0 - 0) >= 0 and abs(nums[0] - nums[0]) >= 0. Hence, a valid answer is [0,0]. Other valid answers are [0,1], [1,0], and [1,1].
Example 3:
Input: nums = [1,2,3], indexDifference = 2, valueDifference = 4 Output: [-1,-1] Explanation: In this example, it can be shown that it is impossible to find two indices that satisfy both conditions. Hence, [-1,-1] is returned.
Constraints:
1 <= n == nums.length <= 105
0 <= nums[i] <= 109
0 <= indexDifference <= 105
0 <= valueDifference <= 109
