Provide tags and a correct Python 3 solution for this coding contest problem. You have a board represented as a grid with 2 × n cells. The first k_1 cells on the first row and first k_2 cells on the second row are colored in white. All other cells are colored in black. You have w white dominoes (2 × 1 tiles, both ce...
