Suppose we allow the pattern P to contain occurrences of a gap character that can match an arbitrary string of characters (even one of zero length). For example, the pattern ab◊ba◊c occurs in the text cabccbacbacab as

and as

Note that the gap character may occur an arbitrary number of times in the pattern but is assumed not to occur at all in the text. Give a polynomial-time algorithm to determine if such a pattern P occurs in a given text T, and analyze the running time of your algorithm.
