Team high scores
Your task
A league's box-score feed has one row per player per team as "team,player,points" (points a non-negative integer; each player appears once). Return a dictionary mapping each team to the highest single-player points on that team. Example: ["hawks,ava,22", "hawks,raj,31", "owls,mia,18"] gives {"hawks": 31, "owls": 18}.
