{ "data": { "question": { "questionId": "1483", "questionFrontendId": "1366", "categoryTitle": "Algorithms", "boundTopicId": 112312, "title": "Rank Teams by Votes", "titleSlug": "rank-teams-by-votes", "content": "
In a special ranking system, each voter gives a rank from highest to lowest to all teams participated in the competition.
\n\nThe ordering of teams is decided by who received the most position-one votes. If two or more teams tie in the first position, we consider the second position to resolve the conflict, if they tie again, we continue this process until the ties are resolved. If two or more teams are still tied after considering all positions, we rank them alphabetically based on their team letter.
\n\nGiven an array of strings votes
which is the votes of all voters in the ranking systems. Sort all teams according to the ranking system described above.
Return a string of all teams sorted by the ranking system.
\n\n\n
Example 1:
\n\n\nInput: votes = ["ABC","ACB","ABC","ACB","ACB"]\nOutput: "ACB"\nExplanation: Team A was ranked first place by 5 voters. No other team was voted as first place so team A is the first team.\nTeam B was ranked second by 2 voters and was ranked third by 3 voters.\nTeam C was ranked second by 3 voters and was ranked third by 2 voters.\nAs most of the voters ranked C second, team C is the second team and team B is the third.\n\n\n
Example 2:
\n\n\nInput: votes = ["WXYZ","XYZW"]\nOutput: "XWYZ"\nExplanation: X is the winner due to tie-breaking rule. X has same votes as W for the first position but X has one vote as second position while W doesn't have any votes as second position. \n\n\n
Example 3:
\n\n\nInput: votes = ["ZMNAGUEDSJYLBOPHRQICWFXTVK"]\nOutput: "ZMNAGUEDSJYLBOPHRQICWFXTVK"\nExplanation: Only one voter so his votes are used for the ranking.\n\n\n

Constraints:
\n\n1 <= votes.length <= 1000
1 <= votes[i].length <= 26
votes[i].length == votes[j].length
for 0 <= i, j < votes.length
.votes[i][j]
is an English uppercase letter.votes[i]
are unique.votes[0]
also occur in votes[j]
where 1 <= j < votes.length
.现在有一个特殊的排名系统,依据参赛团队在投票人心中的次序进行排名,每个投票者都需要按从高到低的顺序对参与排名的所有团队进行排位。
\n\n排名规则如下:
\n\n给你一个字符串数组 votes
代表全体投票者给出的排位情况,请你根据上述排名规则对所有参赛团队进行排名。
请你返回能表示按排名系统 排序后 的所有团队排名的字符串。
\n\n\n\n
示例 1:
\n\n输入:votes = ["ABC","ACB","ABC","ACB","ACB"]\n输出:"ACB"\n解释:A 队获得五票「排位第一」,没有其他队获得「排位第一」,所以 A 队排名第一。\nB 队获得两票「排位第二」,三票「排位第三」。\nC 队获得三票「排位第二」,两票「排位第三」。\n由于 C 队「排位第二」的票数较多,所以 C 队排第二,B 队排第三。\n\n\n
示例 2:
\n\n输入:votes = ["WXYZ","XYZW"]\n输出:"XWYZ"\n解释:X 队在并列僵局打破后成为排名第一的团队。X 队和 W 队的「排位第一」票数一样,但是 X 队有一票「排位第二」,而 W 没有获得「排位第二」。 \n\n\n
示例 3:
\n\n输入:votes = ["ZMNAGUEDSJYLBOPHRQICWFXTVK"]\n输出:"ZMNAGUEDSJYLBOPHRQICWFXTVK"\n解释:只有一个投票者,所以排名完全按照他的意愿。\n\n\n
示例 4:
\n\n输入:votes = ["BCA","CAB","CBA","ABC","ACB","BAC"]\n输出:"ABC"\n解释: \nA 队获得两票「排位第一」,两票「排位第二」,两票「排位第三」。\nB 队获得两票「排位第一」,两票「排位第二」,两票「排位第三」。\nC 队获得两票「排位第一」,两票「排位第二」,两票「排位第三」。\n完全并列,所以我们需要按照字母升序排名。\n\n\n
示例 5:
\n\n输入:votes = ["M","M","M","M"]\n输出:"M"\n解释:只有 M 队参赛,所以它排名第一。\n\n\n

votes[i][j]
是英文 大写 字母votes[i]
中的所有字母都是唯一的votes[0]
中出现的所有字母 同样也 出现在 votes[j]
