The Slicer

[INCOMING — Mission Control, Earth]

Cadet, slicing grabs a chunk of a string instead of one character. The syntax is s[start:end] — start is included, end is not.

s = "ANDROMEDA"
s[0:3]   # "AND"
s[3:7]   # "ROME"
s[-2:]   # "DA"

Telemetry packets always arrive in this exact format (length 30):

TIMESTAMP=YYYY-MM-DDTHH:MM:SSZ

Implement extract(header) that returns a tuple (date, time):

• date = YYYY-MM-DD (10 chars)
• time = HH:MM:SS (8 chars)

Figure out which slice positions hold each piece.

[END TRANSMISSION]

Your Task

In starter/starter.py, return (date, time) extracted with slicing.

Objectives

• extract("TIMESTAMP=2026-05-04T14:32:01Z") → ("2026-05-04", "14:32:01")
• Works for any header in the same fixed format
