<p>You are given a <strong>0-indexed</strong> integer array <code>nums</code> and a target element <code>target</code>.</p> <p>A <strong>target index</strong> is an index <code>i</code> such that <code>nums[i] == target</code>.</p> <p>Return <em>a list of the target indices of</em> <code>nums</code> after<em> sorting </em><code>nums</code><em> in <strong>non-decreasing</strong> order</em>. If there are no target indices, return <em>an <strong>empty</strong> list</em>. The returned list must be sorted in <strong>increasing</strong> order.</p> <p> </p> <p><strong>Example 1:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,5,2,3], target = 2 <strong>Output:</strong> [1,2] <strong>Explanation:</strong> After sorting, nums is [1,<u><strong>2</strong></u>,<u><strong>2</strong></u>,3,5]. The indices where nums[i] == 2 are 1 and 2. </pre> <p><strong>Example 2:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,5,2,3], target = 3 <strong>Output:</strong> [3] <strong>Explanation:</strong> After sorting, nums is [1,2,2,<u><strong>3</strong></u>,5]. The index where nums[i] == 3 is 3. </pre> <p><strong>Example 3:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,5,2,3], target = 5 <strong>Output:</strong> [4] <strong>Explanation:</strong> After sorting, nums is [1,2,2,3,<u><strong>5</strong></u>]. The index where nums[i] == 5 is 4. </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 100</code></li> <li><code>1 <= nums[i], target <= 100</code></li> </ul>
