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

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__.

namespace Treehouse.CodeChallenges { public static class MathHelpers { public static int[][] BuildMultiplicationTable(int maxFactor) { maxFactor++; int[][] result= new int[maxFactor][]; for(int i = 0; i<maxFactor; i++) { result[i] = new int[maxFactor]; for(int j=0; j<maxFactor; j++) { result[i][j] = i*j; } } return result; } } }

5,039 Points@Steven Parker OK, Can you watch this video first"https://teamtreehouse.com/library/jagged-arrays"? After watching it, can you tell me that we can do complete this code challenge? The whole video are done in the console. i still don't know how to do this in the work space.
