Description

Subtract the sum

NOTE! This kata can be more difficult than regular 8-kyu katas (lets say 7 or 6 kyu)

Complete the function which get an input number n such that n >= 10 and n < 10000, then:

1. Sum all the digits of n.
2. Subtract the sum from n, and it is your new n.
3. If the new n is in the list below return the associated fruit, otherwise return back to task 1.

Example

n=325

sum=3+2+5=10

n=325-10=315(not in the list)

sum=3+1+5=9

n=315-9=306(not in the list)

sum=3+0+6=9 n=306-9=297(not in the list)

.

.

.

...until you find the first n in the list below.
