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 JavaScript (node.js v5.12) (judge verdict: Accepted)

'use strict'

function main(input) {

    input = input.split(/\n|\s/).map(v => ~~v)
    const n = input[0]
    const a = input[1]
    const b = input[2]

    let total = 0
    for (let i = 1; i <= n; i++) {

        let tmp = i.toString().split('').map(v => ~~v).reduce((a, b) => a + b)

        if (a <= tmp && tmp <= b) {
            total += i
        }

    }
    console.log(total)

}
main(require("fs").readFileSync("/dev/stdin", "utf8"));
