View as PDFDr. Black has been murdered. Detective Jill must determine the murderer, the location, and the weapon. There are six possible murderers, numbered 1 to 6. There are ten possible locations, numbered 1 to 10. There are six possible weapons, numbered 1 to 6.</p>
For illustration only, we show the names of the possible murderers, locations and weapons. The names are not required to solve the task.

Jill repeatedly tries to guess the correct combination of murderer, location and weapon. Each guess is called a theory. She asks her assistant Jack to confirm or to refute each theory in turn. When Jack confirms a theory, Jill is done. When Jack refutes a theory, he reports to Jill that one of the murderer, location or weapon is wrong.
You are to implement the procedure Solve that plays Jill's role. The grader will call Solve many times, each time with a new case to be solved. Solve must repeatedly call Theory(M,L,W), which is implemented by the grader. M, L and W are numbers denoting a particular combination of murderer, location and weapon. Theory(M,L,W) returns 0 if the theory is correct. If the theory is wrong, a value of 1, 2 or 3 is returned. 1 indicates that the murderer is wrong; 2 indicates that the location is wrong; 3 indicates that the weapon is wrong. If more than one is wrong, Jack picks one arbitrarily between the wrong ones (not necessarily in a deterministic way). When Theory(M,L,W) returns 0, Solve should return.
