[Leetcode] Wildcard Matching

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).

The function prototype should be:
bool isMatch(const char *s, const char *p)

Some examples:
isMatch("aa","a") → false
isMatch("aa","aa") → true
isMatch("aaa","aa") → false
isMatch("aa", "*") → true
isMatch("aa", "a*") → true
isMatch("ab", "?*") → true
isMatch("aab", "c*a*b") → false

只需要依据连续的’*’，将p分割成一些不带’*’的子串。然后在s中依次匹配就好了，只不过需要特殊照顾一下首尾两个子串：
1.对于开头不是’*’的p，第一个子串必须从s[0]开始匹配
2.对于结尾不是’*’的p，最后一个子串必须在s的尾巴上匹配
