It would be great if the description also said that you can choose NO numbers at all. Also, please write “2-by-N grid of numbers” instead of “2 * N grid of numbers” (although that might just be me being nitpicky :wink: ).

Yes It looks like the task description is confusing. “See expect output” allows any “2 D array. First 2 integers R, C are the number of rows and columns”.
Example: "3 4 1 2 3 4 2 3 4 5 1 2 3 4"
1 2 3 4
2 3 4 5
1 2 3 4
allows get al least 10 (4+2+4) instead of reported by the button 8.
