    738 - Monotone Increasing Digits.

    Medium

    An integer has monotone increasing digits if and only if each pair of adjacent digits x and y satisfy x <= y.

    Given an integer n, return the largest number that is less than or equal to n with monotone increasing digits.

    Example 1:

    Input: n = 10

    Output: 9

    Example 2:

    Input: n = 1234

    Output: 1234

    Example 3:

    Input: n = 332

    Output: 299

    Constraints:

    • 0 <= n <= 109
