0.00/0.50	Problem:
0.00/0.50	even(0()) -> true()
0.00/0.51	even(s(x)) -> true() <= odd(x) = true()
0.00/0.51	odd(s(x)) -> true() <= even(x) = true()
0.00/0.51	
0.00/0.51	Proof:
0.00/0.51	This system is confluent.
0.00/0.51	By \cite{SMI95}, Corollary 4.7 or 5.3.
0.00/0.51	This system is oriented.
0.00/0.51	This system is of type 3 or smaller.
0.00/0.51	This system is right-stable.
0.00/0.51	This system is properly oriented.
0.00/0.51	This is an overlay system.
0.00/0.51	This system is left-linear.
0.00/0.51	All 0 critical pairs are trivial or infeasible.
