44 - Wildcard Matching.

Hard

Given an input string (s) and a pattern (p), implement wildcard pattern matching with support for '?' and '*' where:

• '?' Matches any single character.
• '*' Matches any sequence of characters (including the empty sequence).

The matching should cover the entire input string (not partial).

Example 1:

Input: s = “aa”, p = “a”

Output: false

Explanation: “a” does not match the entire string “aa”.

Example 2:

Input: s = “aa”, p = “*”

Output: true

Explanation: ‘*’ matches any sequence.

Example 3:

Input: s = “cb”, p = “?a”

Output: false

Explanation: ‘?’ matches ‘c’, but the second letter is ‘a’, which does not match ‘b’.

Example 4:

Input: s = “adceb”, p = “*a*b”

Output: true

Explanation: The first ‘*’ matches the empty sequence, while the second ‘*’ matches the substring “dce”.

Example 5:

Input: s = “acdcb”, p = “a*c?b”

Output: false

Constraints:

• 0 <= s.length, p.length <= 2000
• s contains only lowercase English letters.
• p contains only lowercase English letters, '?' or '*'.
