I wanted for a long time to solve Advent Of Code. But december is always too busy for me. So I took my time and solved 8 out of the 25 days of each 2 assignments in my own pace and without getting help.
I am coding in Python and it works like a charm. I am happy to be reunited with Numpy and other packages :-)
I guess I will choose another language next time.
