Leetcode 248. Strobogrammatic Number III
Count how many strobogrammatic numbers (numbers that read the same when rotated 180°) lie within a given numeric range [low, high] (often provided as strings). Solve by recursively constructing valid strobogrammatic strings of each length using mirrored digit pairs, while avoiding leading zeros and using string-based comparisons to enforce the range.
