2,685 PointsJagged and MD array exercises failing despite solution working in Visual Studio
Hi,
For both of these exercises, I am getting the below message:
"The table should contain 6 rows and 6 columns"
I can run the same code in VS (albeit using console output commands) and I get the desired results. The jagged array code:
public static int[][] BuildMultiplicationTable(int maxFactor) { int[][] sheet = new int[maxFactor][];
for(int row = 0; row < sheet.Length; row++)
{
sheet[row] = new int[maxFactor];
for(int column = 0; column < sheet[row].Length; column++)
{
sheet[row][column] = row * column;
}
}
return sheet;
}
Guessing I am missing something obvious but the function is expecting the array itself to be returned, not a console output.
Thanks.

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.
You're really close, though. The issue is that your table is too small. To accommodate values up to and including maxFactor, the array dimensions (in both directions) will need to be maxFactor + 1
since the values begin at 0.
