#2. Design and implement a prolog clp program (puzzple2.pl), to output all the solutions as a result (not one solution after the other as a part of query by typing a semicolon).

Your program should print a heading stating the total number of the solutions found.

[Note. You may like to use findall/3 here or you may solve the problem case by case to collect each the solution, then to be output.]

You may use the sample code (as your base code) provided in Weekly Activity for CLP (and/or a few sample codes discussed in the class).
