***** CLARIFICATIONS *****
(problem 1): The path traces out the boundary of a convex polygon.

(problem 4): The students want to find routes to class that don't intersect at any *intersection*.

(problem 4): The sample output is wrong for the first case.  It should read:
     Case 1:
     1 3 2
     1 4 2
     1 5 2

(problem 6): All labels fit in a 32-bit signed integer.

(problem 7): half-point available if you solve problem correctly when no quarters or 20-dollar bills. Time to get the half-point is not counted, but it does count toward penalty time if you solve the problem properly later.

half-point receivers: rumenov, emarion

(minor clarification): The contest software uses the -O2 option when compiling C and C++ submissions.  i.e.:
     g++ -O2 -o probX probX.cc (for C++)
     gcc -O2 -o probX probX.c -lm (for C)
