def Array.insertionSort.traverse {α : Type u_1} (lt : α → α → Bool) (a : Array α) (i fuel : Nat) : Array α

Equations

• Array.insertionSort.traverse lt a i 0 = a
• Array.insertionSort.traverse lt a i fuel_2.succ = if h : i < a.size then Array.insertionSort.traverse lt (Array.insertionSort.swapLoop lt a i h) (i + 1) fuel_2 else a

def Array.insertionSort.swapLoop {α : Type u_1} (lt : α → α → Bool) (a : Array α) (j : Nat) (h : j < a.size) : Array α

Equations

• Array.insertionSort.swapLoop lt a 0 h = a
• Array.insertionSort.swapLoop lt a j'.succ h = if lt a[j'.succ] a[j'] = true then Array.insertionSort.swapLoop lt (a.swap ⟨j'.succ, h⟩ ⟨j', ⋯⟩) j' ⋯ else a
