:) sorry, you are right

Are you sure? "10003" is lexicographically smaller than "22", isnt it?
Which of these two comes first when sorted in dictionary/lexicographical/alpbabetical order?

but string '10003' > '22'

Float parameter "bounce" must be greater than 0 and less than 1

Float parameter "window" must be less than h

Your code is wrong for those conditions.

Not a kata issue, read the conditions in the description again.

.

The weight of a number will be from now on the sum of its digits.

When two numbers have the same "weight", let us class them as if they were strings (alphabetical ordering) and not numbers

11 comes before 2000 because it's sorted like a word, comparing characters starting from the left: "1" comes before "2".
10003 comes after 11 and 2000 because 1 + 1 and 2 + 0 + 0 + 0 are 2, and 1 + 0 + 0 + 0 + 3 is 4.
