9.1.7 Checkerboard V2 Answers -

That is a correct checkerboard — so maybe the “interesting feature” is something else. Given the title “Checkerboard ” and many students asking about this, the interesting feature might be: The checkerboard works correctly only when you use if ((row + col) % 2 == 0) but you must ensure the row’s first character is consistent with the parity of row and col = 0. If you accidentally start both even and odd rows with # , the board will not alternate properly — it will produce vertical stripes instead. But vertical stripes happen when you always start with # regardless of row parity — so the “feature” is a bug that becomes a teachable moment. A better guess from real CodeHS answers: Many students who post “9.1.7 checkerboard v2 answers — interesting feature” online point out: When you print the board, the rows look shifted relative to each other because of the space in front of every other row. This creates a visual “zigzag” edge on the left side of the board. That visual effect (odd rows starting with space, even with # ) is the interesting feature. If you paste your code or describe the exact “interesting feature” you observed , I can give a precise explanation.

Actually, without offset but with (r + c) % 2 :

It seems you’re referring to a specific puzzle or exercise labeled — likely from a coding course (such as CodeHS, AP CSA, or a similar Java/JavaScript tutorial) — and you’re noticing “an interesting feature” in the output.

Row 0 (r=0): #_#_#_#_ (where _ is space) Row 1 (r=1): _#_#_#_# Row 2: #_#_#_#_ Row 3: _#_#_#_#
