Tournament Standings

Rank teams from match records.

問題

Rank teams from match records. Each record has the form First;Second;result, with no extra spaces. Result is win, loss, or draw from First’s perspective. A win earns 3 points, a draw earns 1 per team, and a loss earns 0. Count matches played, wins, draws, losses, and points for each team that appears. Sort by descending points, then ascending team name (ASCII order).

Return one semicolon-separated row per team: Name;Played;Won;Drawn;Lost;Points. Do not include a header or alignment spaces.

Implement tournament_standings(matches).

Input

matches: Match records, in any order.

Output

Return ranked rows with the six fields described above. Write numbers without leading zeros.

制約

0…10,000 valid records. Team names contain 1…30 ASCII letters and are case-sensitive. Each match has two different names. Repeated matches are separate games. Empty input gives an empty result.

例

例 1
入力:
matches = ["Falcons;Bears;win", "Bears;Owls;draw"]

期待される出力:
expected = ["Falcons;1;1;0;0;3", "Bears;2;0;1;1;1", "Owls;1;0;1;0;1"]
入力:
std::vector<std::string> matches = {"Falcons;Bears;win", "Bears;Owls;draw"};

期待される出力:
std::vector<std::string> expected = {"Falcons;1;1;0;0;3", "Bears;2;0;1;1;1", "Owls;1;0;1;0;1"};
入力:
string[] matches = new string[] {"Falcons;Bears;win", "Bears;Owls;draw"};

期待される出力:
string[] expected = new string[] {"Falcons;1;1;0;0;3", "Bears;2;0;1;1;1", "Owls;1;0;1;0;1"};

解説

Falcons have 3 points from their win. Bears and Owls each have 1 point from the draw, so Bears come first alphabetically. Bears played twice and lost once.

例 2
入力:
matches = ["Zebras;Ants;loss"]

期待される出力:
expected = ["Ants;1;1;0;0;3", "Zebras;1;0;0;1;0"]
入力:
std::vector<std::string> matches = {"Zebras;Ants;loss"};

期待される出力:
std::vector<std::string> expected = {"Ants;1;1;0;0;3", "Zebras;1;0;0;1;0"};
入力:
string[] matches = new string[] {"Zebras;Ants;loss"};

期待される出力:
string[] expected = new string[] {"Ants;1;1;0;0;3", "Zebras;1;0;0;1;0"};

解説

Loss is from Zebras’ perspective: Ants won and receive 3 points. Zebras receive 0.
