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){
  var N = parseInt(input.split(' ')[0]);
  var A = parseInt(input.split(' ')[1]);
  var B = parseInt(input.split(' ')[2]);

  var sum = 0;
  for(var i = 1; i <= N; i++){
    var is = i.toString().split('')
      .map((a) => parseInt(a, 10)).reduce((b, c) => { return b + c });
    
    if(A <= is && is <= B){
      sum += i;
    }
  }
  console.log(sum);
}

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