https://leetcode.com/problems/wildcard-matching/#/description
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 package go.jacob.day708; /** * 44.
