Proof step 2 from proof bits2int-zero-01 (previous step)

⊦ bits = [], bits2int(bits) = 0, true ∈ bits

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ bits.first ∧ bits ≠ [] → bits2int(bits) = bits2uint(bits.rest)
Proof step 4:
¬(¬ bits.first ∧ bits ≠ []) ⊦ bits = [], bits2int(bits) = 0, true ∈ bits
Proof step 6:
¬ bits.first ∧ bits ≠ [] ⊦ bits = [], bits2uint(bits.rest) = 0, true ∈ bits

Rule argument

name: bits2int-pos-01 rotate: F subst: [bits] → [bits]
