Questions

Lab

How would you check the sum?

Try sum-of-file with a simpler file.

Open the file, copy and paste into a spreadsheet, then sum.

In DrRacket, open the file, insert (+ at the beginning, insert ')' at the end, click "Run"

Why would you check the sum?

Historical evidence suggests that we often get an "off by one" error when doing computations (e.g., we might miss the first or last value).

What's the writeup?

Exercise 6. This is class 44.
