I discovered Acepta el Reto while studying for my higher vocational qualification in Multiplatform Application Development, almost a decade ago. Back then, I took part in a programming competition with some classmates, solving problems in Java.

I remember that experience quite fondly: nerves, trial and error, getting stuck now and then, and that small geeky satisfaction when the judge finally accepted a solution.

Now I’ve decided to return to it, this time solving the problems in C. The idea is to make it a small weekly routine: keep practising logical thinking, revisit basics that are worth keeping fresh — types, arrays, structures, input and output, efficiency and edge cases — and, along the way, enjoy those challenges that make you think before you start coding.

I’ll be uploading my C solutions to this GitHub repository: Acepta el Reto in C.

Sometimes the problem isn’t about writing more code, but finding the right approach.
