Thus, 0 is not a k-distant index.\n- For index 1, |1 - 2| &lt;= k and nums[2] == key, so 1 is a k-distant index.\n- For index 2, |2 - 2| &lt;= k and nums[2] == key, so 2 is a k-distant index.\n- For index 3, |3 - 2| &lt;= k and nums[2] == key, so 3 is a k-distant index.\n- For index 4, |4 - 5| &lt;= k and nums[5] == key, so 4 is a k-distant index.\n- For index 5, |5 - 5| &lt;= k and nums[5] == key, so 5 is a k-distant index.\n- For index 6, |6 - 5| &lt;= k and nums[5] == key, so 6 is a k-distant index.\n</code>Thus, we return [1,2,3,4,5,6] which is sorted in increasing order. \n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> nums = [2,2,2,2,2], key = 2, k = 2\n<strong>Output:</strong> [0,1,2,3,4]\n<strong>Explanation:</strong> For all indices i in nums, there exists some index j such that |i - j| &lt;= k and nums[j] == key, so every index is a k-distant index. \nHence, we return [0,1,2,3,4].\n</pre>\n\n<p>&nbsp;</p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 &lt;= nums.length &lt;= 1000</code></li>\n\t<li><code>1 &lt;= nums[i] &lt;= 1000</code></li>\n\t<li><code>key</code> is an integer from the array <code>nums</code>.</li>\n\t<li><code>1 &lt;= k &lt;= nums.length</code></li>\n</ul>\n",
