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: Runtime Error)

function verifier(n::Int, a::Int, b::Int)
    sumLevel = 0
    while n != 0
        sumLevel += n % 10
        n = div(n, 10)
    end

    if (a <= sumLevel <= b)
        true
    else
        false
    end
end

prior(a, b) = n -> verifier(n, a, b)

n, a, b = parse.(Int, split(readline()))
nums = [ x for x = 1:n ]

filter(prior(a, b), nums)

println(result |> sum)
