### (1) DecreasingLoopProof (EQUIVALENT transformation)

The following loop(s) give(s) rise to the lower bound Ω(2n):
The rewrite sequence
rev2(X, cons(Y, L)) →+ cons(rev1(X, rev(rev2(Y, L))), rev2(X, rev(rev2(Y, L))))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0,1,0].
The pumping substitution is [L / cons(Y, L)].
The result substitution is [X / Y].

The rewrite sequence
rev2(X, cons(Y, L)) →+ cons(rev1(X, rev(rev2(Y, L))), rev2(X, rev(rev2(Y, L))))
