bool Utility::isSubstring	(	string	sub,
		string	s
	)

Check whether sub is the substring of s.

bool b = isSubstring("", "a") => true
bool b = isSubstring("bc", "abc") => true

bool b = isSubstring("", "") => true
bool b = isSubstring("", "a") => true
bool b = isSubstring("bc", "abc") => true

substringFirstIndex()

int Utility::substringFirstIndex	(	string	sub,
		string	s
	)

find the index of sub in string s

• If sub is empty, then return -1
• If found sub is the sub of s, then return the first index in s

substringFirstIndex("", "a") => -1
substringFirstIndex("a", "ba") => 1
