K-TH SMALLEST IN LEXICOGRAPHICAL ORDER | POTD | JAVA SOLUTION | HARD PROBLEM |
Hello Everyone, Welcome to my YouTube channel.
In this video, we dive into the problem of finding kth smallest number in lexicographical order in the range [1, n]. We start by discussing the brute force approach, which has a time complexity of O(n). However, the goal is to achieve an O(logK) solution with minimal extra space.
we dive deep into the problem of finding the kth lexicographically smallest integer. We'll explore different approaches, starting from brute force and gradually moving towards optimized solutions.
Key Topics Covered:
Understanding Lexicographical Order: We'll clarify what it means for a number to be lexicographically smaller than another.
Brute Force Approach: A straightforward but inefficient method involving generating all numbers and sorting.
Optimized Solution: We'll present a more efficient algorithm that leverages the properties of lexicographical order.
Code Walkthrough: Step-by-step explanation of the code implementation, making it easy to follow.
Time and Space Complexity Analysis: We'll analyze the performance of both approaches.
