If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Finish the solution so that it returns the sum of all the multiples of 3 or 5 below the number passed in.
Note: If the number is a multiple of both 3 and 5, only count it once.

})Count the number of occurrences of each character and return it as a list of tuples in order of appearance. For empty output return an empty list.
Example:
'''
OrderedCount("abracadabra") == []Tuple{Tuple{'a', 5}, Tuple{'b', 2}, Tuple{'r', 2}, Tuple{'c', 1}, Tuple{'d', 1}}
// Where
type Tuple struct {
Char rune
Count int
