Check if Array is Sorted and Rotated 🔍🔥 | LeetCode 1752 Explained Step by Step
📌 LeetCode 1752 – Check if Array Is Sorted and Rotated (Easy)
In this video, we solve LeetCode Problem 1752: Check if Array Is Sorted and Rotated 🔄.
We’ll understand the problem step by step, build the core intuition, and learn how to identify whether an array is sorted and then rotated without actually rotating it.
✨ What you’ll learn in this video:
What does sorted and rotated really mean 🤔
How rotation makes the array circular 🔁
Why counting order breaks is the key idea 🧠
Handling edge cases and duplicate elements
Writing an efficient O(n) solution in C++ 🚀
🧪 We’ll also dry-run tricky test cases like:
[3,4,5,1,2]
[2,1,3,4]
[1,1,1]
📈 Time Complexity: O(n)
📦 Space Complexity: O(1)
