The Translator

[INCOMING — Mission Control, Earth]

Cadet, when input comes in as text (a str), you can't do math with it directly. You have to translate it to a number.

Three converters:

• int("42") → 42
• float("3.14") → 3.14
• str(42) → "42"

Implement years_until(age) that returns 100 - age as an int. The argument may arrive as either int or str — handle both by calling int() on it first.

[END TRANSMISSION]

Your Task

Open starter/starter.py. Convert age with int(), then return 100 - age.

Objectives

• years_until(25) returns 75
• years_until("25") also returns 75 (handles string input)
• Works for any integer age 0–100
