Find the Remainder

Description

Task:

Write a function that accepts two integers and returns the remainder of dividing the larger value by the smaller value.

Division by zero should return an empty value.

Examples:

n = 17
m = 5
result = 2 (remainder of `17 / 5`)

n = 13
m = 72
result = 7 (remainder of `72 / 13`)

n = 0
m = -1
result = 0 (remainder of `0 / -1`)

n = 0
m = 1
result - division by zero (refer to the specifications on how to handle this in your language)

My Solution

def remainder(a, b)
  return nil if a == 0 || b == 0
  return a.abs % b.abs if a >= b
  b.abs % a.abs if b >= a
end
