LeetCode 367 - Valid Perfect Square | Binary Search Explained 🔥

🚀 In this video, I solved LeetCode 367 - Valid Perfect Square using an efficient Binary Search approach with an easy explanation.

This problem helps improve understanding of Binary Search and mathematical optimization, which are common in coding interviews.

📌 Problem Statement:

Given a positive integer num, return:

true if num is a perfect square
false otherwise

A perfect square is an integer that can be written as:

x × x = num

You must solve this without using built-in sqrt().

⚡ Time Complexity:

O(log n)

⚡ Space Complexity:

O(1)

🎯 Concepts Used:
• Binary Search
• Math Optimization
• Perfect Squares
• Searching Algorithms
• DSA Patterns

🔥 Why learn this problem?

This problem teaches how to apply Binary Search beyond arrays, an important interview skill.
