Problem:
 f(h(b(),c())) -> c()
 a() -> h(h(h(f(a()),b()),h(c(),c())),f(b()))
 h(f(a()),a()) -> h(c(),a())
 b() -> b()
 h(h(b(),f(b())),h(a(),c())) -> b()

Proof:
 Uncurry Processor:
  f5(f(),f5(f5(h(),b()),c())) -> c()
  a() -> f5(f5(h(),f5(f5(h(),f5(f5(h(),f5(f(),a())),b())),f5(f5(h(),c()),c()))),f5(f(),b()))
  f5(f5(h(),f5(f(),a())),a()) -> f5(f5(h(),c()),a())
  b() -> b()
  f5(f5(h(),f5(f5(h(),b()),f5(f(),b()))),f5(f5(h(),a()),c())) -> b()
