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"

const main =(input)=>{
  const array =input.split(" ")
  const N = array[0]-0
  const A = array[1]-0
  const B = array[2]-0
  
  let result = 0;
  for (let i=0; i<=N; i++){
   const sum= i.toString().split("").reduce( (a,b)=>(a-0)+(b-0) )
    if (A<=sum && B>=sum) result+=i ;
  }
  console.log(result);
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'))
