P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: First, collect all the scores for each team into lists. Then divide by the number of games to find the average score.

# Step 1: Get all team scores together 

1) Create an empty "scores" dict to hold a list of scores for each team
2) For each "game" dict in the the input
  a) If team is not in "scores":
    i) Map team -> empty list in "scores"
  b) Append score to team -> list in "scores"

# Step 2: Find the highest average score

3) Highest average starts at 0, best team starts at None
4) For each team, score-list in "scores" dict
  a) Get average of score-list
  b) If average is higher than current highest
    i) Replace current highest
   ii) Update best team
5) Return best team
