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 arr = input.split(' ').map(x => Number(x));
  var total = 0;

  for (var i = 1; i <= arr[0]; i++) {
    var sum = Array.from(String(i)).map(x => Number(x)).reduce((a,c) => a + c);
    if (arr[1] <= sum && sum <= arr[2]) {
      total += i;
    }
  }

  console.log(total);
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
