<p>Even though I like this solution a lot, as I already mentioned at <a href="https://py.checkio.org/mission/sort-array-by-element-frequency/publications/flpo/python-3/-itemscountx-itemsindexx/share/8e0f7a4c7f89f63390eeb4f5ef6ab95d/">https://py.checkio.org/mission/sort-array-by-element-frequency/publications/flpo/python-3/-itemscountx-itemsindexx/share/8e0f7a4c7f89f63390eeb4f5ef6ab95d/</a>#comment-70506</p> <p>This solution is more than 10 times slower than using Counter.</p>
