## Goal

Given two integers, `low` and `high`, return how many **strobogrammatic numbers** are present in that range, inclusive.

A **strobogrammatic number** is a number whose numeral is **rotationally symmetric**, so that it appears the same when rotated **180 degrees**. In other words, the numeral looks the same right-side up and upside down (e.g., 69, 96, 1001).

The first few **strobogrammatic numbers** are:

0, 1, 8, 11, 69, 88, 96, 101

Input

**Line 1:** The `lower` integer of the range

**Line 2:** The `higher` integer of the range

Output

**Line 1:** The number of **strobogrammatic numbers** in the range

Constraints

0 ≤ `low` ≤ 10¹⁷

0 ≤ `high` ≤ 10¹⁷

`low` ≤ `high`
