Bing
From Wikicliki
I know. You're thinking, who on earth uses Bing? Some who's accidentally bought a windows laptop for the first time and had to use Bing to find Google so they could reset their browser's default search to Google? Oh wait that was me five minutes ago.
Turns out that Bing is great for Programming snippets. The internet says its also used by people who want to find porn and pirated materials.
In Singapore SafeSearch is turned on (zzz). You need to switch region to United Kingdom under Settings to see Hackerrank's helpful additions, which are EXECUTABLE! Did you hear that? EXECUTABLE!
Oh is python not your thing? WELL JUST SEE IT IN ALL THESE LANGUAGES
So next time someone asks you who uses Bing? Its PROGRAMMERS, PORN USERS & PIRATES! :-D
