    386 - Lexicographical Numbers\. Medium Given an integer `n`, return all the numbers in the range `[1, n]` sorted in lexicographical order. You must write an algorithm that runs in `O(n)` time and uses `O(1)` extra space. **Example 1:** **Input:** n = 13 **Output:** [1,10,11,12,13,2,3,4,5,6,7,8,9] **Example 2:** **Input:** n = 2 **Output:** [1,2] **Constraints:** * 1 <= n <= 5 * 104
