14,775 PointsBuildMultiplicationTable returned null
The table is costructed properly. It is printed out on the console as i shoud but I still get "BuildMultiplicationTable returned null". I'm stuck...
using System;
namespace Treehouse.CodeChallenges
{
public static class MathHelpers
{
public static int[][] BuildMultiplicationTable(int maxFactor)
{
int[][] table = new int[maxFactor + 1][];
for (int i = 0; i < maxFactor; i++)
{
table[i] = new int[maxFactor + 1];
for (int j = 0; j < maxFactor; j++)
{
table[i][j] = i * j;
}
}
for (int i = 0; i < maxFactor; i++)
{
for (int j = 0; j < maxFactor; j++)
{
Console.Write(table[i][j]);
}
Console.WriteLine();
}
return table;
}
}
}

231,198 PointsThe challenge asks you to return the table, it doesn't require you to print anything.
Also, you have allocated adequate space to create a table up to and including "maxFactor", but your loops stop short of it when setting the values.

14,775 Points- I did "console.write" to see what the table has inside.
- I can't understand the part "your loops stop short of it when setting the values". What do you mean by that?
