match vs search vs fullmatch

Easy ⏱ 8 min 82% acceptance ★★★★★ 4.6

Write where_digit(text) returning a tuple of three booleans: does r'\d+' produce a hit with re.match (start-anchored), re.search (anywhere), and re.fullmatch (entire string)? For 'ab12' that is (False, True, False) — the distinction interviews love.

Example 1

Input

Output

Explanation

Digits exist but neither start nor span the whole string.

Constraints

Use all three functions.
Convert results to bool.
