MAYBE

Problem:
 f(x,f(y,a())) -> f(f(f(f(a(),x),y),a()),h(a()))

Proof:
 DP Processor:
  DPs:
   f#(x,f(y,a())) -> f#(a(),x)
   f#(x,f(y,a())) -> f#(f(a(),x),y)
   f#(x,f(y,a())) -> f#(f(f(a(),x),y),a())
   f#(x,f(y,a())) -> f#(f(f(f(a(),x),y),a()),h(a()))
  TRS:
   f(x,f(y,a())) -> f(f(f(f(a(),x),y),a()),h(a()))
