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: Wrong Answer)

function Main(input) {
  var In = input.split(' ');
  var N = In[0];
  var A = In[1];
  var B = In[2];
  
  var sum = 0;
  
  for(var i = 1; i <= N; i++){
    var str = String(i);
    var array = str.split('');
    var length = array.length;
    var strSum = 0;
    
    for(var j = 0; j < length; j++){
      var num = parseInt(array[j], 10);
      strSum += num;
    }
    
    if(A <= strSum){
      if(strSum <= B){
        sum += strSum;
      }
    }
  }
  
  console.log(sum);
  
}

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