This series will be focused on Coding interview questions curated from various interviews / via online source.
There are n citizens voting in this year’s Hackland election. Each voter writes the name of their chosen candidate on a ballot and places it in a ballot box. The candidate with the highes number of votes win the election; if two or more candidates have the same number of votes, then the tied candidates’ names are ordered alphabetically and the last name wins.

- 1<= n <= 10^4
Input Format An array of Strings
Output Format Name of the person who has the max votes. If there are multiple people with same number of votes(max) then print the last name of the list arranged in dictionary order.
