Given a 5x5 matrix representing the “house” at the end of a curling round, determine which team scores and how many points they score.
The layout:
- The center cell (index
[2, 2]) is the “button”.
- The 8 cells directly surrounding the button represent ring 1.
- And the 16 cells on the outer edge of the house represent ring 2.
In the given matrix:
"." represents an empty space."R" represents a space with a red stone."Y" represents a space with a yellow stone.
Scoring rules:
- Only one team can score per round.
- The team with the stone closest to the button scores.
- The scoring team earns 1 point for each of their stones that is closer to the button than the opponent’s closest stone.
- The lower the ring number, the closer to the center the stone is.
- If both teams’ closest stone is the same distance from the center, no team scores.
Return:
- A string in the format
"team: number_of_points". e.g: "R: 2".
- or
"No points awarded" if neither team scored any points.
For example, given:
[
[".", ".", "R", ".", "."],
[".", "R", ".", ".", "."],
["Y", ".", ".", ".", "."],
[".", "R", ".", ".", "."],
[".", ".", ".", ".", "."]
]
Return "R: 2". The two red stones in ring 1 are tied for the closest and are the only two stones closer than yellows closest.
