738. Monotone Increasing Digits
Problem Link: 738. Monotoen Increasing Digits
Givan a non-negative integer N, find the largest number that is less than or equal to N and whose digits are monotonically increasing. An integer is monotonically increasing if for every adjacent pair of digits, x <= y.
Example 1:
Input: N = 10
Output: 9
