A visual artist is programming an 8x8 LED display:

This is their program so far:

rowNum ←  0
REPEAT 5 TIMES
{
   colNum ← 0
   REPEAT (5 - rowNum) TIMES
   {
     fillPixel(rowNum, colNum, "red")
     colNum ← colNum + 1
    }
    rowNum ← rowNum + 1
}

The code relies on this procedure:

fillPixel(row, column, color) : Lights up the pixel at the given row and column with the given color (specified as a string). The top row is row 0 and the left-most column is column 0.

What will the output of their program look like?
