Problem: Lexicographical Numbers

Medium
30 min
Explore how to list numbers from 1 to n in lexicographical order, also called dictionary order. Understand the problem constraints and challenge yourself to implement an optimal O(n) time and space solution. This lesson helps strengthen algorithmic thinking applicable in coding interviews.

Statement

Given an integer value nn, write a function that returns all the numbers in the range 11 to nn in lexicographical orderLexicographical order, also known as dictionary order or alphabetical order, is a way of ordering sequences (such as strings) based on the order of their elements. .

Constraints:

  • 1≤n≤1031 \leq n \leq 10^3
