The interviewer wanted to see the answer to the algorithm question done in demo-able, live code and he gave me the choice of using either coderpad or my Xcode IDE. You're given the assignment to implement your own regular expression parser with three different cases: exact_match, wildcard_match and then an exact_wildcard_match (if I remember correctly). The API should look something like this: exact_match("hello world","hello") returns true exact_match(hello world","llo") returns true (llo exists) The first parameter is the string and the second parameter is the query you're doing the matching on. The wildcard in the wildcard match was a period, so a successful (true) "wildcard_match" could have inputs such as ("hello world",".ello") (where the wildcard character is a period).
