Associative Arrays

• Introduction
• Operations
  • AssociativeArray() → Assoc
  • AssociativeArray(I): Str → Assoc
  • A[x] := y: Assoc, Elt, Elt
  • A[x]: Assoc, Elt → Elt
  • IsDefined(A, x): Assoc, Elt → Bool, Elt
  • IsInKeys(A, x): Assoc, Elt → Bool, Elt
  • Remove(~A, x): Assoc, Elt
  • Universe(A): Assoc → Str
  • # A: Assoc → RngIntElt
  • Keys(A): Assoc → SetEnum
  • Values(A): Assoc → List
  • Example: Assoc Creation
• Iteration
  • v in A
  • k -> v in A
  • Example: Assoc Iteration
