<# .SYNOPSIS Determines the subgrid number of the current placement attempt .DESCRIPTION Based on row and column, determines the . .PARAMETER Row The row of the placement to attempt, this must be in the range 1-9 .PARAMETER Column The number to be tried, must be in the range 1-9 .EXAMPLE CaclulateSubgrid -Row 1 -Column 1 #would return 0th subgrid .INPUTS Takes in a row and column .OUTPUTS Returns a number indicating the subgrid number #> Function CalculateSubgridNumber { param ( [parameter(Mandatory=$true)] [ValidateRange(1, 9)] [int32]$Row, [parameter(Mandatory=$true)] [ValidateRange(1, 9)] [int32]$Column ) if ($Row -lt 4) { # in the first row of subgrids if ($Column -lt 4) { # in the first column of subgrids return 0 } elseif ($Column -lt 7) { # in the second column of subgrids return 1 } else { # in the third column of subgrids return 2 } } elseif ($Row -lt 7) { #in the 2nd row of subgrids if ($Column -lt 4) { # in the first column of subgrids return 3 } elseif ($Column -lt 7) { # in the second column of subgrids return 4 } else { # in the third column of subgrids return 5 } } else { #in the 3rd row of subgrids if ($Column -lt 4) { # in the first column of subgrids return 6 } elseif ($Column -lt 7) { # in the second column of subgrids return 7 } else { # in the third column of subgrids return 8 } } } |
