Question

Use python

Answer 1

Answer:

def rec_dig_sum( num ):

   num_list = [ digit for digit in str(num)]

   total = 0

   for x in num_list:

       total += x

   return total

def dict_of_rec_dig_sums(low, high):

   mydict = dict()

   for number in the range(low, high+1):

      mydict[rec_dig_sum(number)] = number

   return mydict

Explanation:

The python program defines two functions, "rec_dig_sum" and "dict_of_rec_dig_sums". The former accepts a number and returns the sum of the digits of the number while the latter accepts a low and high number range.

The program returns a dictionary with the recursive sum as the keys and the number count as the values.
