The Counter

[INCOMING — Mission Control, Earth]

Cadet, time to count things in text. Three counts:

• Total length — len(s)
• Word count — len(s.split()) (split breaks on whitespace)
• a count — s.lower().count("a") returns how many as

Implement count(s) that returns a dict with three keys:

• length — total chars including spaces
• words — word count
• a_count — number of lowercase as after lowercasing

[END TRANSMISSION]

Your Task

In starter/starter.py, build the dict using len(), .split(), .lower(), .count().

Objectives

• count("Hello andromeda") → {"length": 15, "words": 2, "a_count": 2}
• All three keys present and correct for any sentence
