## Problem J4: Favourite Times

Wendy has an LED clock radio, which is a 12-hour clock, displaying times from `12:00` to `11:59`. The hours do not have leading zeros but minutes may have leading zeros, such as `2:07` or `11:03`.

When looking at her LED clock radio, Wendy likes to spot arithmetic sequences in the digits. For example, the times `12:34` and `2:46` are some of her favourite times, since the digits form an arithmetic sequence.

A sequence of digits is an arithmetic sequence if each digit after the first digit is obtained by adding a constant common difference. For example, 1,2,3,4 is an arithmetic sequence with a common difference of 1, and 2,4,6 is an arithmetic sequence with a common difference of 2.

Suppose that we start looking at the clock at noon (that is, when it reads `12:00`) and watch the clock for some number of minutes. How many instances are there such that the time displayed on the clock has the property that the digits form an arithmetic sequence?

### Input Format

The input contains one integer D (0 ≤ D ≤ 1 000 000 000), which represents the duration that the clock is observed.

For 4 of the 15 available marks, D ≤ 10000.

### Output Format

Output the number of times that the clock displays a time where the digits form an arithmetic sequence starting from noon (`12:00`) and ending after D minutes have passed, possibly including the ending time.

```1
```

### Explanation 1

Between `12:00` and `12:34`, there is only the time `12:34` for which the digits form an arithmetic sequence.

```180
```

```11
```

### Explanation 2

Between `12:00` and `3:00`, the following times form arithmetic sequences in their digits (with the difference shown):

• `12:34` (difference 1),
• `1:11` (difference 0),
• `1:23` (difference 1),
• `1:35` (difference 2),
• `1:47` (difference 3),
• `1:59` (difference 4),
• `2:10` (difference −1),
• `2:22` (difference 0),
• `2:34` (difference 1),
• `2:46` (difference 2),
• `2:58` (difference 3).
