Your question is DOE File Reading with Limited RAM (Large Data). Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
In DOE, how would I read a large file that contains multiple GBs of data if I have 2 GB of RAM and how would I make the reading process take less time/ faster?
