    1291 - Sequential Digits.

    Medium

    An integer has sequential digits if and only if each digit in the number is one more than the previous digit.

    Return a sorted list of all the integers in the range [low, high] inclusive that have sequential digits.

    Example 1:

    Input: low = 100, high = 300

    Output: 123,234

    Example 2:

    Input: low = 1000, high = 13000

    Output: 1234,2345,3456,4567,5678,6789,12345

    Constraints:

    • 10 <= low <= high <= 10^9
