-This homework assignment requires the knowledge from Module 3.
+To be announced.
-==== Please write a regular expression for matching the sequence of numbers which follows these rules: ====
-) The sequence consists of one or more parts. If there are two or more parts,
-they are separated with a comma (",") character.
-) Each part of the sequence is either an integer or a real number.
-An integer number consists of one or more digits and must not begin with
-zero ("0"), unless the integer number has only one digit.
-If the part of the sequence is a real number, it consists of one or more
-digits which are followed by one punctuation mark ("."), with this
-punctuation mark being followed by one or more digits. Like the integer
-number, the real number must not begin with zero ("0"), unless there is
-only one digit before the punctuation mark. Also, the real number must
-not end with zero ("0"), unless there is only one digit after the punctuation
-mark.
-Please note that for accomplishing the task, one regular expression has
-to be submitted which is suitable for use with the '''egrep''' or '''pcregrep''' tool.
-It is not acceptable to submit the solution in a fragmented way (e.g.,
-several isolated expressions for addressing different parts of the task).
-Also, it is not allowed to submit programs in Java, Python, Perl (or any
-other language) for the solution.
-'''Examples of sequences the regular expression must match:'''
-                (the sequence has one valid integer part)
-,2.35             (the sequence has two valid parts - an integer and a real number)
-.205,754.0          (the sequence has two valid real number parts)
-.4,12,0.1           (the sequence has three valid parts - a real number integer, and a real number)
-,1.0,3,4.8,0.0,0,7.001,8.0      (the sequence has eight valid parts)
-'''Examples of sequences the regular expression must NOT match:'''
-, 2          (the second part begins with a space character which is illegal)
-2,3         (the first part contains a space character which is illegal)
-.0,          (the first part ends with comma, but there is no following second part)
-F            (the number contains an illegal character F)
-            (the integer number has more than one digit and begins with a zero which is illegal)
-.00          (the real number has more than one digit after the punctuation mark and ends with a zero which is illegal)
--1           (the number contains an illegal character -)
-,,8.9        (the second part of the sequence is empty)
-.            (the real number contains a punctuation mark without at least one following digit)
- .3            (the real number contains a punctuation mark without at least one preceding digit)
-.43.222      (the real number illegally contains two punctuation marks)
