Thanks for your reply.
I m implementing Sudoku that computer will play after the user inputs certain numbers in its grid. The logic that I m following is that the function PossibleNumbers() calculates the numbers that are possible for each cell of 9x9 grid of Sudoku.The number of numbers possible for each cell may Vary. If for example 1, 3 are numbers possible for one cell, then 2,3,4 maybe possible for other cell.PossibleNumbers() runs for every cell of the grid. Here is its implementation

private int[] PossibleNumbers()
{ int[] PossibleNumbers = new int[] { 1, 2, 3, 4, 5, 6 };
Array.Clear(PossibleValues, 0, 6);
int k = 0;

for (int i=0 ; i < PossibleNumbers.Length; i++)
{
int count = 0;
for (int j=0 ; j < tempArray.Length; j++)
{
if (tempArray[j] == Convert.ToInt32(PossibleNumbers[i]))
{
count++;
break;
}
}
if (count == 0)
{
PossibleValues[k] = PossibleNumbers[i];
k++;
}
}
return PossibleValues;
}

The size of PossibleValues is set to 6 at the time of initializing it.so if two numbers are possible for a cell then the remaining 4 indexes will contain zero. And this is the problem. How do I go about it.

Please Help!
Thanks
