You are given two strings. Determine if the second string is a substring of the first (Do NOT use any substr type library function). The second string may contain an asterisk(*) which should be treated as a regular expression i.e. matches zero or more characters. The asterisk can be escaped by a \ char in which case it should be interpreted as a regular '*' character. To summarize: the strings can contain alphabets, numbers, * and \ characters.
Your program should accept as its first argument a path to a filename. The input file contains two comma delimited strings per line. E.g.
Hello,ell This is good, is CodeEval,C*Eval Old,Young
If the second string is indeed a substring of the first, print out a 'true'(lowercase), else print out a 'false'(lowercase), one per line. E.g.
true true true false
