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") → falseisMatch("aa","aa") → trueisMatch("aaa","aa") → falseisMatch("aa", "*") → trueisMatch("aa", "a*") → trueisMatch("ab", "?*") → trueisMatch("aab", "c*a*b") → false

class Solution {

public:
  bool isMatch(const char *s, const char *p) 
{
    if (s == NULL || p == NULL) return false;
    if (*p == '\0') return *s == '\0';
    
    if (*p == '*')
    {
        while (*p == '*') ++p;
        
        while (*s != '\0')
        {
            if (isMatch(s, p)) return true;
            ++s;
        }
        
        return isMatch(s, p);
    }
    else if ((*s != '\0' && *p == '?') || *p == *s)
    {
        return isMatch(s + 1, p + 1);
    }
    
    return false;
}
};
