Challenge Task 1 of 1

Return a multiplication table consisting of an array of arrays. The table should contain all of the products of integers from 0 to maxFactor. For example, if maxFactor is 3 the resulting multiplication table should contain the following: 0 0 0 0 0 1 2 3 0 2 4 6 0 3 6 9

It looks like you asked this three times.

Here are the hints I gave on the original question:

  • you don't need to write to the console, just build and return the table.
  • you might need a second loop nested inside the first to handle both dimensions.
  • it's a multiplication table — don't forget to multiply.

I don't get it either. I can't see any similarity between the 9-minute video and the challenge.

Do you have to type this below?

csharp> class Cell

{ public string Contents { get; set; } ?
