My friend John and I are members of the "Fat to Fit Club (FFC)". John is worried because
each month a list with the weights of members is published and each month he is the last on the list
which means he is the heaviest. 

I am the one who establishes the list so I told him:
"Don't worry any more, I will modify the order of the list".
It was decided to attribute a "weight" to numbers. The weight of a number will be from now on
the sum of its digits. 

For example `99` will have "weight" `18`, `100` will have "weight"
`1` so in the list `100` will come before `99`.
Given a string with the weights of FFC members in normal order can you give this string ordered by "weights" of these numbers?

# Example:

`"56 65 74 100 99 68 86 180 90"` ordered by numbers weights becomes: 
`"100 180 90 56 65 74 68 86 99"`

When two numbers have the same "weight", let us class them as if they were strings (alphabetical ordering) and not numbers:
`100` is before `180` because its "weight" (1) is less than the one of `180` (9)
and `180` is before `90` since, having the same "weight" (9),  it comes before as a *string*.

All numbers in the list are positive numbers and the list can be empty.

# Notes

- it may happen that the input string have leading, trailing whitespaces and more than a unique whitespace between two consecutive numbers
- Don't modify the input
- For C: The result is freed.
