Welcome to Day 1 of my LeetCode Challenge! In this video, I tackle the 'Missing Number' problem, a common interview question that tests your problem-solving skills. Watch as I break down the problem, explain my thought process, and implement the solution in Python. Whether you're preparing for coding interviews or just love coding, this video is for you!


🔍 Problem Description:
Given an array nums containing n distinct numbers in the range [0, n], return the only number in the range that is missing from the array.

👨‍💻 Code Along:

Problem-solving approach
Python coding implementation
Debugging and testing the solution
📈 Problem Solving Important Aspects:

Understanding the Problem: Clearly define the problem and what is expected in the solution.
Formulating a Plan: Devise a strategy to solve the problem, considering multiple approaches.
Implementing the Solution: Write clean, efficient code to implement the chosen approach.
Testing and Debugging: Test the solution with various cases to ensure its correctness and handle any edge cases.
Optimization: Explore ways to enhance the performance of the solution, discussing time and space complexity.

🧠 Explanation:

Approach 1: Using the sum formula to find the missing number.
Approach 2: Sorting and binary search method.
