(1) DecreasingLoopProof (EQUIVALENT transformation)

The following loop(s) give(s) rise to the lower bound Ω(n¹):
The rewrite sequence
f(x, y, mark(z)) →⁺ mark(f(x, y, z))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0].
The pumping substitution is [z / mark(z)].
The result substitution is [ ].
