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 myout(text){console.log(text);}//standard output
function Main(input) {
	//input = parseInt(input.trim());
	//input = input.trim().split(" ");
	//input = input.trim().split("\n");
	input = input.trim().split(" ").map((a)=>Number(a));
	//input = input.trim().split("\n").map((a)=>Number(a));
  var N = input[0];
  var A = input[1];
  var B = input[2];
  var output = 0;
  for(var i = 1; i <= N; i++){
    var tmp = i.toString().split("");
    var digitSum = 0;
    for(var j = 0; j < tmp.length; j++){
      digitSum += parseInt(tmp[j]);
    }
    if(digitSum >= A && digitSum <= B){
       output += i;
       }
  }
  myout(output);
}

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