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
