I completely agree. I eliminated all basic issues in my coding skills a few years ago by doing a lot of online challenges. Drawing an analogy to writers, online challenges (or preparing for them) is like getting really good at sentence formation, vocabulary, paragraph formation, etc. This allows you to then focus on larger things like writing a paper and even comprehending other people's papers with much ease. Code is the language of software engineering and computer science. Online competitions help internalize that so that it becomes second nature.
