Who won the match?

Given the score for a tennis match, your program should print which player (player 1 or player 2) won the match. Here is an example run:

$ python3 tennis_scores.py "6-4 6-4"
Player 1 won the match

$ python3 tennis_scores.py "4-6 4-6"
Player 2 won the match

$ python3 tennis_scores.py "4-6 6-4 4-6"
Player 2 won the match

$ python3 tennis_scores.py "6-4 5-7 6-4"
Player 1 won the match

You can assume that the scores will be given as a single string as shown above so you need to split the string to get scores for individual sets. You need to further split the set score to find the games won by each player.

Even though examples above show scores for best of 3 sets match, your program should work for best of 5 sets as well, such as this:

$ python3 tennis_scores.py "6-4 5-7 6-4 7-6"
Player 1 won the match

Bonus points if you can handle invalid input and print error message as follows:

$ python3 tennis_scores.py "6-4 5-7 6-4 6-7"
Invalid input
