Programming : project euler

[nekoexmachina]

So not sure why, but this gem: https://projecteuler.net/ has not yet mentioned on this website, ever.

 

This is a set of programming/mathematical challenges. One can solve most challenges the dumb way, or the smart way, and dumb way usually takes exponentially more time then the smart way. 

 

One of best things I've done there was cutting time the program runs to solve the issue from ~33 minutes to 1.5 seconds, just changing algorithm in a small way.

 

I'd propose anyone who has interest in mathematics or in code to take part. 

It has more to do with mathematics then with code, but still is very useful to any type of developers.
