220. Contains Duplicate III

You are given an integer array nums and two integers indexDiff and valueDiff.

Find a pair of indices (i, j) such that:

• i != j,
• abs(i - j) <= indexDiff.
• abs(nums[i] - nums[j]) <= valueDiff, and

Return true if such pair exists or false otherwise.

Example 1:

Input: nums = [1,2,3,1], indexDiff = 3, valueDiff = 0
Output: true
Explanation: We can choose (i, j) = (0, 3).
We satisfy the three conditions:
i != j --> 0 != 3
abs(i - j) <= indexDiff --> abs(0 - 3) <= 3
abs(nums[i] - nums[j]) <= valueDiff --> abs(1 - 1) <= 0

Example 2:

Input: nums = [1,5,9,1,5,9], indexDiff = 2, valueDiff = 3
Output: false
Explanation: After trying all the possible pairs (i, j), we cannot satisfy the three conditions, so we return false.

Constraints:

• 2 <= nums.length <= 105
• -109 <= nums[i] <= 109
• 1 <= indexDiff <= nums.length
• 0 <= valueDiff <= 109
