How to iterate through jagged array?

Question

int[][,] arr=new int[3][,];
arr[0]=new int[2,3]{{1,1,1},{2,2,2}};
arr[1]=new int[1,2]{{3,3}};
arr[2]=new int[3,3]{{4,4,4},{5,5,5},{6,6,6}};

design algorithm please

Answer 1

Got it! Missed the comma:

foreach(int[,] intArr in arr)
{
foreach(int num in intArr)
{
Console.WriteLine(num);
}
}

This should work. Full code here:

Answer 2

Something like:

foreach(int[] intArr in arr)
{
foreach(int num in intArr)
{
Console.WriteLine(num);
}
}

I don't know. This makes my head hurt. I try to stay away from jagged arrays if possible, they quickly become complex.

Answer 3
