Proof step 6 from proof bytes2int-zero-06 (previous step)

∀ by. by ∈ bytes → b2i(by) = 0 ⊦ bytes2int(bytes) = 0, bytes = []

User applied rule induction

And obtained the following new goals

Proof step 7:
∀ by. by ∈ bytes → b2i(by) = 0, ∀ bytes0. # bytes0 < # bytes → (∀ by. by ∈ bytes0 → b2i(by) = 0) → bytes2int(bytes0) = 0 ∨ bytes0 = [] ⊦ bytes2int(bytes) = 0 ∨ bytes = []

Rule argument

indvar: # bytes wfpred: <

Additional information

Used simplifier rules: <; (wellfounded) Used terms: # bytes
