Algorithms

You are given a 0-indexed integer array <code>nums</code> and a target element <code>target</code>.

A target index is an index <code>i</code> such that <code>nums[i] == target</code>.

Return a list of the target indices of <code>nums</code> after sorting <code>nums</code> in non-decreasing order. If there are no target indices, return an empty list. The returned list must be sorted in increasing order.

&nbsp;
Example 1:

<pre>
Input: nums = [1,2,5,2,3], target = 2
Output: [1,2]
Explanation: After sorting, nums is [1,2,2,3,5].
The indices where nums[i] == 2 are 1 and 2.
</pre>

Example 2:

<pre>
Input: nums = [1,2,5,2,3], target = 3
Output: [3]
Explanation: After sorting, nums is [1,2,2,3,5].
The index where nums[i] == 3 is 3.
</pre>

Example 3:

<pre>
Input: nums = [1,2,5,2,3], target = 5
Output: [4]
Explanation: After sorting, nums is [1,2,2,3,5].
The index where nums[i] == 5 is 4.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= nums.length &lt;= 100</code></li>
	<li><code>1 &lt;= nums[i], target &lt;= 100</code></li>
</ul>
