Proof step 2 from proof bytes2int-zero-03 (previous step)

bytes2int(bytes) = 0, by ∈ bytes ⊦ by = i2b(0)

User applied rule induction

And obtained the following new goals

Proof step 3:
bytes2int(bytes) = 0 ∧ by ∈ bytes, ∀ by, bytes0. # bytes0 < # bytes → bytes2int(bytes0) = 0 ∧ by ∈ bytes0 → by = i2b(0) ⊦ by = i2b(0)

Rule argument

indvar: # bytes wfpred: <

Additional information

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