Please solve the programming task below using a self-contained code snippet in a markdown code block.

Given two strings low and high that represent two integers low and high where low <= high, return the number of strobogrammatic numbers in the range [low, high].
A strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down).
 
Please complete the following python code precisely:
```python
class Solution:
    def strobogrammaticInRange(self, low: str, high: str) -> int:
```
