I just started on the ‘Intro to Indexing’ mission from the ‘Advance SQL for Data Analysis’ and I was wondering when we learned any of this stuff (example below)? What is the order I’m supposed to follow here? I’m on step 4 course 3 and in it, it says ‘If i need a refresher I should head to Algorithms mission,’ a mission btw that is in step 8 course 2. Am i not supposed to follow the course structure? If not, what structure am I supposed to follow?
On slide 1 we get this PRAGMA function that I was expected to know even though I’ve never heard of it.
Then O(log N) time complexity or whatever that is was introduced and explained on the slide after with assumption of previous knowledge.
I just don’t understand this mission whatsoever.
