# [386. Lexicographical Numbers](https://leetcode.com/problems/lexicographical-numbers/)
## 题目:
Given an integer n, return 1 - n in lexicographical order.
For example, given 13, return: [1,10,11,12,13,2,3,4,5,6,7,8,9].
Please optimize your algorithm to use less time and space. The input size may be as large as 5,000,000.
## 题目大意
给定一个整数 n, 返回从 1  n 的字典顺序。例如给定 n =13返回 [1,10,11,12,13,2,3,4,5,6,7,8,9] 。
请尽可能的优化算法的时间复杂度和空间复杂度。 输入的数据 n 小于等于 5,000,000。
## 解题思路
- 给出一个数字 n ,要求按照字典序对 1-n 这 n 个数排序。
- DFS 暴力求解即可。
