# 1. Count number from `DATA` by the category:
#    - 'small' - number between 0 and 3 (lower included, upper excluded)
#    - 'medium' - number between 3 and 7 (lower included, upper excluded)
#    - 'large' - number between 7 and 10 (lower included, upper excluded)
# 2. Run doctests - all must succeed
