386. Lexicographical Numbers

Leetcode Solutions

Initialize an empty list result to store the lexicographically ordered numbers.
Start with current number as 1.
Use a loop to iterate until you have added n numbers to the result list.
Add the current number to the result list.
If current * 10 is less than or equal to n, multiply current by 10.
Else, if current is not the last number in its group (i.e., its last digit is not 9) and current + 1 is less than or equal to n, increment current by 1.
Else, divide current by 10 until the last digit is not 9, then increment current by 1.
Repeat steps 4-7 until the result list contains n numbers.
