// A visual artist is programming a 7x7 LED display:
// 7x7 grid of squares.
// This is their program so far:
// rowNum ← 1
// numPixels ← 1
// REPEAT 3 TIMES
// {
//    colNum ← 5 - rowNum
//    REPEAT (numPixels) TIMES
//    {
//      fillPixel(rowNum, colNum, "green")
//      colNum ← colNum + 1
//     }
//     numPixels ← numPixels + 2
//     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 1 and the left-most column is column 1.
// What will the output of their program look like?
