# Our football team finished the championship. The result of each match look like "x:y". Results of all matches are recorded in the collection.

# For example: ["3:1", "2:2", "0:1", ...]

# Write a function that takes such collection and counts the points of our team in the championship. Rules for counting points for each match:

# if x>y - 3 points
# if x<y - 0 point
# if x=y - 1 point
# Notes:

# there are 10 matches in the championship
# 0 <= x <= 4
# 0 <= y <= 4
