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)

function main(input) {
  const args = input.split(' ');
  const N = parseInt(args[0]);
  const A = parseInt(args[1]);
  const B = parseInt(args[2]);
  
  const nums = Array.from(new Array(N), (v, i) => ++i).filter((i) => {
  	var n = i.toString().split('').reduce((p, c) => p + parseInt(c), 0);
    return (A <= n && n <= B);
  });
  
  console.log(nums.reduce((p, c) => p + c, 0));
}

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