A strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down).

Find all strobogrammatic numbers that are of length = n.

Example:

Input:  n = 2
Output: ["11","69","88","96"]

Hint 1

Try to use recursion and notice that it should recurse with n - 2 instead of n - 1.
