    2048 - Next Greater Numerically Balanced Number.

    Medium

    An integer x is numerically balanced if for every digit d in the number x, there are exactly d occurrences of that digit in x.

    Given an integer n, return the smallest numerically balanced number strictly greater than n.

    Example 1:

    Input: n = 1

    Output: 22

    Explanation:

    22 is numerically balanced since:

    • The digit 2 occurs 2 times.

    It is also the smallest numerically balanced number strictly greater than 1.

    Example 2:

    Input: n = 1000

    Output: 1333

    Explanation:

    1333 is numerically balanced since:

    • The digit 1 occurs 1 time.

    • The digit 3 occurs 3 times.

    It is also the smallest numerically balanced number strictly greater than 1000. Note that 1022 cannot be the answer because 0 appeared more than 0 times.

    Example 3:

    Input: n = 3000

    Output: 3133

    Explanation:

    3133 is numerically balanced since:

    • The digit 1 occurs 1 time.

    • The digit 3 occurs 3 times.

    It is also the smallest numerically balanced number strictly greater than 3000.

    Constraints:

    • <code>0 <= n <= 10<sup>6</sup></code>
