I'm currently job hunting and looking for a platform to prep for interviews.

Leetcode is nice but it locks hard problems behind a paywall that I honestly can't afford right now.

I mean I can still read the problem from https://leetcode.ca/, but it's hard to test it against a good set of test cases.

Please share alternative portals with a decent hard problem collection with testcases

This is usually found in really cheap products and looks and sounds metallic (rings a bit when dropped) , but I'm not sure if it is one.

The pictured cross section shows the greyish metal (the gold is just paint).

The cross section feels coarse and has tiny glittering specks. It also looks a bit porous (tiny air bubbles seem to be present in this alloy)

It's also pretty weak - a pencil like object made from this stuff can easily be snapped in two with your bare hands.

Thanks!

This is shamelessly stolen from some other community on Lemmy. I can't find that post anymore but I'd be happy to link it here if anyone does know.
