input: Write a function to find all the numbers divisible by a certain number within a certain range. The function should take three parameters: the start of the range (m), the end of the range (n), and the divisor. Return a list of numbers that are divisible by the divisor within the specified range.
  assert find_numbers_divisible_by(36, 74, 6)==[36, 42, 48, 54, 60, 66, 72]
  assert find_numbers_divisible_by(10, 50, 5)==[10, 15, 20, 25, 30, 35, 40, 45, 50]
  assert find_numbers_divisible_by(20, 30, 7)==[21, 28]
  assert find_numbers_divisible_by(1, 10, 1)==[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  assert find_numbers_divisible_by(1, 1, 2)==[]
output: def find_numbers_divisible_by(m, n, divisor):
      return [i for i in range(m, n+1) if i % divisor == 0]
