  2. Hi Yu,
    It looks like two problems point to the same solution:
    Regular Expression Matching
    Wildcard Matching

    Problem statements look similar but approaches are different.
    At very least consider the following case:
    Regex: isMatch("aab", "c*a*b") -> true
    Wildcard: isMatch("aab", "c*a*b") - false

    Please revisit :)
