Questions and Answers

Which method does the ivy.Container class use for the add operator?

  • operator.add (correct)
  • operator.div
  • operator.mul
  • operator.sub

What happens when the add operator is called on two ivy.Array instances?

  • The add operator is not supported for ivy.Array instances
  • The add operator calls operator.sub for each corresponding leaf of the two arrays
  • The add operator calls operator.add for each corresponding leaf of the two arrays (correct)
  • The add operator calls operator.mul for each corresponding leaf of the two arrays

What happens when the add operator is called on a mix of ivy.Container and ivy.Array instances?

  • The add operator calls operator.mul for each corresponding leaf of the two containers/arrays
  • The add operator is not supported for a mix of ivy.Container and ivy.Array instances
  • The add operator calls operator.add for each corresponding leaf of the two containers/arrays (correct)
  • The add operator calls operator.sub for each corresponding leaf of the two containers/arrays
