Problem Statement

Find the sum of the integers between 1 and N (inclusive), whose sum of digits written in base 10 is between A and B (inclusive).

Constraints

1 \leq N \leq 10^4

1 \leq A \leq B \leq 36

All input values are integers.

Input

Input is given from Standard Input in the following format:

N A B

Output

Print the sum of the integers between 1 and N (inclusive), whose sum of digits written in base 10 is between A and B (inclusive).

Sample Input 1

20 2 5

Sample Output 1

84

Among the integers not greater than 20, the ones whose sums of digits are between 2 and 5, are: 2,3,4,5,11,12,13,14 and 20. We should print the sum of these, 84.

Sample Input 2

10 1 2

Sample Output 2

13

Sample Input 3

100 4 16

Sample Output 3

4554

Solution in Julia (0.5.0) (judge verdict: Accepted)

parseInt(x) = parse(Int, x)

function ss(n)
	m = n
	sum = 0
	for i in 1:5
		sum +=m%(10)
		m = div(m, 10)
	end
	return(sum)
end

function main()
	n = readline() |> split |> x -> parseInt.(x)
	sum = 0
	for i in 1:n[1]
		if n[2] <= ss(i) <= n[3]
			sum += i
		end
	end
	print(sum)
end

main()
