An 8x8 grid representing a house. Row 1: 3 white, 2 black, 3 white. Row 2: 2 white, 4 black, 2 white. Row 3: 1 white, 6 black, 1 white. Row 4: 8 black. Row 5: 2 white, 4 black, 2 white. Row 6: 2 white, 4 black, 2 white. Row 7: 2 white, 4 black, 2 white. Row 8: 2 white, 4 black, 2 white.

Give the result of compressing the first 4 rows of the icon using Run-Length Encoding (RLE).

You should:

Represent each run of pixels as the number of pixels followed by the color character (e.g., 5W for 5 white pixels).
Encode each row individually, separating rows with a comma or a new line.
