Solution: Rank Teams by Votes
Understand how to solve ranking problems by tracking vote counts for each team efficiently. Learn to implement a 2D array to count votes per rank, sort teams by vote precedence, and handle ties alphabetically. This lesson helps you practice key problem-solving patterns used in coding interviews.
We'll cover the following...
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.
