- Wildcard Matching（通配符匹配）
Given an input string (s) and a pattern §, implement wildcard pattern matching with support for ‘?’ and ‘*’.
‘?’ Matches any single character.
‘*’ Matches any sequence of characters (including the empty sequence).
The matching should cover the entire input string (not partial).
Note:
s could be empty and contains only lowercase letters a-z.
p could be empty and contains only lowercase letters a-z, and characters like ? or *.
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 = “ab”
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
