Termination w.r.t. Q of the following Term Rewriting System could be proven:

Q restricted rewrite system:
The TRS R consists of the following rules:

f(f(X)) → c
cd
h(X) → c

Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:

f(f(X)) → c
cd
h(X) → c

Q is empty.

We use [27] with the following order to prove termination.

Knuth-Bendix order [24] with precedence:
c > d

and weight map:

c=1
f_1=1
d=1
h_1=1
