Problem: Rank Teams by Votes

med
30 min
Understand how to rank teams by evaluating votes using a multi-level system. Learn to track first-place votes and resolve ties through subsequent positions and alphabetical order. Practice implementing this ranking approach to master tracking data, managing permutations, and solving related coding problems.

Statement

Assume a ranking system where each gives a rank to all competing teams from highest to lowest. The final ranking is decided on the basis of the number of first-place votes they receive. If there’s a tie for first place, the second-place votes are used to break the tie; if there’s still a tie, the third-place votes are considered, and this continues until all positions have been evaluated. If teams remain tied after all positions have been reviewed, they are ranked alphabetically by their team names.

Given an array of strings votes that represents the rankings given by all voters, sort the teams according to the specified ranking system and return a string that lists all the teams in the ranked order.

Constraints:

  • 11 \leq votes.length 1000\leq 1000

  • 11 \leq votes[i].length 26\leq 26

  • votes[i].length == votes[j].length for 00 \leq i, j << votes.length

  • votes[i][j] is an uppercase English letter.

  • All characters of votes[i] are unique.

  • All characters present in votes[0] are also found in votes[i] where 11 \leq i << votes.length.
