Problem set 1 done.
The Mario exercise was pretty straightforward, but the credit card one took me way longer than expected.
Mainly due to all the things that C doesn't do out of the box and I had to code myself.
But the feeling when seeing this console is 10/10!
Essentially, we had to implement “Luhn’s Algorithm” for validating credit card numbers. It was pretty interesting, learning about this one.
And it involved doing way more math than I expected. I guess with the intro to arrays next week, the whole task would've been easier.
