Original Highlight Excerpt
"a comparison sort cannot perform better than O(n log n) on average"
Whisper Note
So that's why my custom sort is always slower than the built-in.

Original Highlight Excerpt
"the output of any sorting algorithm must satisfy two conditions"
Whisper Note
Even the definition sounds like a math test I'd fail.

"the output of any sorting algorithm must satisfy two conditions"
Whisper Note
So that's why my custom sort broke — missed condition two.

Two conditions? I thought it was just 'small to big' and done.

Whisper Note
Guess my bubble sort is officially doomed then.

"stable sorting algorithms maintain the relative order of records with equal keys"
Whisper Note
Doesn't matter much for numbers, but with objects it's a lifesaver.

Whisper Note
That's the whole reason I use stable sorts for leaderboards, ties feel fairer.

"puts elements of a list into an order"
Whisper Note
I always just use sort() and hope it's fast enough.

"puts elements of a list into an order"
Whisper Note
But what about stable vs unstable? That's the real debate.

Basically the whole point of sorting, yeah.
