Add, Subtract, Multiply or Divide?

Published by Matt in

Write a function that takes two numbers and returns if they should be added, subtracted, multiplied or divided to get 24. If none of the operations can give 24, return nil.

Examples

operation(15, 9) ➞ "added"

operation(26, 2) ➞ "subtracted"

operation(11, 11) ➞ nil

Notes

  • Only integers are used as test input.
  • Numbers should be added, subtracted, divided or multiplied in the order they appear in the parameters.
  • The function should return either "added", "subtracted", "divided", "multiplied" or nil.
