Each day I solve several challenges and puzzles from Codr's ranked mode. The goal is to reach genius rank, along the way I explain how I solve them. You do not need any programming background to get started, but you will learn a ton of new and interesting things as you go.
In this post I'll cover two challenges because the first one is a quick one:
The first challenge requires us to figure out R's initial value (βοΈ). But because this value gets overwritten later in the code, so the initial value doesn't matter. But it must be a boolean to pass our validation criteria, so either true or false are correct.
Let's proceed to the next challenge:
This one is a bit more exciting. We need to figure out π and βοΈ, both identifiers, such that R=11. To find π you need to analyze the for-loop, it contains a variable N which hasn't been declared yet, so π is most likely going to be N. The identifier for βοΈ doesn't matter much, because if you look at the last line of code R=arr.length, the challenge is only interested in the number of items in the array, not what those values actually are. So βοΈ should ideally be N or i.
