I did my first Euler problem on 3 July 2017 in Scratch, and have now (November 2018) done 65, including all of the first 50, mostly in Python.
I am not sharing any of my code because Project Euler asks you not to.
The highest difficulty problem I have done was number 82 (minimum path through an 80x80 grid when you can travel in three directions) which was ranked 20%. I used dynamic programming.
I have also done 16 Project Euler Problems in C.
I also like the Bebras and Oxford Computing challenges and the 100 Programming challenges on GitHub (links below).
