Hello everyone! I just released an AWESOME new tool and I'm here to spread the word.↵

Introducing...↵

PS/CP Toolkit --> [biximo.net](https://biximo.net) <--↵
======================================================↵

So, what is this thing?↵
-----------------↵

If you’ve ever done competitive programming (CP) or problem solving (PS), you probably know how annoying it can be to do certain things manually. And while you'd think there’d be a convenient website with all the tools in one place... turns out, nope. No one made one.↵

So I did.↵

PS Toolkit V1 is packed with useful number theory tools — and more features are on the way! Please check it out and share if you find it helpful!↵
