The fastest horse The fastest horse
RU English

We have some horse racing statistics (each horse’s time in each race)
You have to find the number of the horse which has the most wins.
For example: if the results are [[“1:13”, “1:26”, “1:11”], [“1:10”, “1:18”, “1:14”], [“1:20”, “1:23”, “1:15”]] then the 3rd horse is the fastest, because it has won 2 races out of 3.
Every element in the list - is a string in format m:ss, for example, "1:05" or "2:22". 1:00 <= time <= 5:00

example

Input: Racing time as an array of arrays.

Output: The number of the fastest horse that has the most wins (Important: in this task the horse numbers starts from "1", not from "0")

Example:

fastest_horse([[“1:13”, “1:26”, “1:11”], [“1:10”, “1:18”, “1:14”], [“1:20”, “1:23”, “1:15”]]) == 3

How it is used: For data analysis and statistics (finding the needed elements in the huge amount of data).

Precondition:
2 <= horses <= 10
1 <= races <= 10
1:00 <= time <= 5:00
There is only 1 fastest horse in each test
