<p>You are given a <strong>0-indexed</strong> integer array <code>nums</code> having length <code>n</code>, an integer <code>indexDifference</code>, and an integer <code>valueDifference</code>.</p> <p>Your task is to find <strong>two</strong> indices <code>i</code> and <code>j</code>, both in the range <code>[0, n - 1]</code>, that satisfy the following conditions:</p> <ul> <li><code>abs(i - j) >= indexDifference</code>, and</li> <li><code>abs(nums[i] - nums[j]) >= valueDifference</code></li> </ul> <p>Return <em>an integer array</em> <code>answer</code>, <em>where</em> <code>answer = [i, j]</code> <em>if there are two such indices</em>, <em>and</em> <code>answer = [-1, -1]</code> <em>otherwise</em>. If there are multiple choices for the two indices, return <em>any of them</em>.</p> <p><strong>Note:</strong> <code>i</code> and <code>j</code> may be <strong>equal</strong>.</p> <p> </p> <p><strong class="example">Example 1:</strong></p> <pre> <strong>Input:</strong> nums = [5,1,4,1], indexDifference = 2, valueDifference = 4 <strong>Output:</strong> [0,3] <strong>Explanation:</strong> 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. </pre> <p><strong class="example">Example 2:</strong></p> <pre> <strong>Input:</strong> nums = [2,1], indexDifference = 0, valueDifference = 0 <strong>Output:</strong> [0,0] <strong>Explanation:</strong> 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]. </pre> <p><strong class="example">Example 3:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,3], indexDifference = 2, valueDifference = 4 <strong>Output:</strong> [-1,-1] <strong>Explanation:</strong> In this example, it can be shown that it is impossible to find two indices that satisfy both conditions. Hence, [-1,-1] is returned.</pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= n == nums.length <= 10<sup>5</sup></code></li> <li><code>0 <= nums[i] <= 10<sup>9</sup></code></li> <li><code>0 <= indexDifference <= 10<sup>5</sup></code></li> <li><code>0 <= valueDifference <= 10<sup>9</sup></code></li> </ul>
