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.
Examples
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
