## Digits Sum

The filter accepts tickets that have the sum of their *first* and/or *last digits* in the selected range. Each pool number breaks down into two
digits. The *first digit *is the leading digit of the number, the *last
digit *is the second digit of the number. For example the first digit of number
23 is 2, the last digit of that number is 3. The first digit of number
9 is 0, the last digit of that number is 9.

### Example

When filter settings are *Sum of first and last digits is min: 25 max: 25 *then

- 01-02-03-04-05-19 - filter accepts this ticket because the sum of its first digits is 1 and the sum of its last digits is 24. So the total sum of all digits is 25.
- 01-02-03-04-05-29 - filter rejects this ticket because the sum of all its digits is 26 which is outside the allowed range.

When filter settings are *Sum of first digits is min: 0 max: 0 *then

- 01-02-03-04-05-09 - filter accepts this ticket because all its numbers are lower than 10 so the sum of first digits is 0.
