Could someone please fix my code so that these methods run and makes my teris bricks deltete once one of the rows are full and makes the row above move down? This is not my full code I just provided what I thought was neccessary to get this part correct.

$$ rowHasSpace$($ int rowNumber$)-$ returns true if there

is a space in the row of the board. This is used to determine

if the row is full and needs scoring.

$$ rowHasColor$($ int rowNumber$)-$ return true if there is

color in row of the board. This would be used to detect the

end point of shifting rows down.

$$ copyRow$($int rowNumber$)-$ copy row content to the row

below. Used to shift a row down when a full row is scored.

The method affectively over writes the content of the row

below, making the deletion of this row unnecessary, unless

of course you want to go for extra credit and make some

special effect that shows the bricks imploding or something

equally dramatic. :$0)$

$$ copyAllRows$($int rowNumber$)-$ calls the method

copyRow on each row starting with rowNumber and above

$($located higher in the well, or at a lower row number$)$

rowHasSpace$($ int rowNumber$)-$ returns true if there

is a space in the row of the board. This is used to determine

if the row is full and needs scoring.

A suggested approach uses the following pseudo code copyAllRows:

$1.$Determine the range of rows to be checked.

$2.$ currentRow $-$ highest row number in range

$2.$ REPEAT for each row within the range starting with max

$3.$ IF rowHasSpace$($ int rowNumber$)$ is false

$4.$ call copyAllRows$($currentRow$)$

$5.$ current row is incremented $($so that when for loop

decrements current, it remains the same

$6.$ min row of range is decremented

$7.$ END IF

$8.$END REPEAT

Based off of this:
