Hello there, here is something tricky i just can’t get it. In this exercise, you need to take the data from a csv and fill in the blanks at rpachallenge.com
The thing is, why are we iterating for each row when we need to go throught the columns ? There is no column iteration at the exercise. And we need to go through columns becouse that is where the data is.
The question is:
- Why are we iterating through rows when we also need columns ?
- How do we go through the columns if we are only going through rows ?
Here are some images for better understanding.
