Wildcard Pattern Matching

HardPython

Problem

A Voleon research pipeline uses compact patterns to select text-based instrument labels. Given a string s and a pattern p, determine whether the entire string matches the entire pattern.

The pattern contains lowercase English letters, *, and ?:

  1. A letter matches exactly the same letter.
  2. * matches one or more arbitrary characters.
  3. ? matches zero or one arbitrary character.
  4. Matching must cover all characters in both s and p.

Return True if the string matches the pattern, otherwise return False.

Formal Specification

Implement wildcard_match(s, p), where both inputs are strings. Return a Boolean.

Constraints

  • 0 <= len(s) <= 2,000
  • 0 <= len(p) <= 2,000
  • s and p contain only lowercase English letters, '*' and '?'
  • A '*' wildcard must match at least one character
  • Matching is required for the entire string and entire pattern

Function Signature
