2,440 PointsI need to include the [0,0] row and column and I can't work out how.
I have coded up a basic multiplication matrix. However, to complete the challenge I need to include the first row and columns of 0. I have tried everything that I can think of. Any help to solve this (fairly simple issue I can't crack) is greatly received.
Thanks

public static int[][] BuildMultiplicationTable(int maxFactor)
{
int[][] multiplicationTable = new int[maxFactor][];
for (int row = 1; row <= maxFactor; row++)
{
multiplicationTable[row - 1] = new int[row];
for (int col = 1; col <= row ; col++)
{
multiplicationTable[row - 1][col - 1] = row * col;
}
}
return multiplicationTable;
}
}
}

231,198 PointsThe overall function structure is good, but you have some values issues:
- the loops should start at 0 instead of 1
- the rows will need to have
maxFactor
plus one items - the columns will need to be the same size as the rows (instead of the row itself)
- the indexes need to remain inside the range
