Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Rotate String | s+s Substring Trick (O(n)) | Part 222 [Hindi]

📘 Welcome to Part 222 of Code & Debug’s DSA in Python Course! In this quick strings pattern, check if goal is a rotation of s. The optimal idea is elegant: every rotation of s appears as a substring of s+s, so rotation reduces to a length check plus a substring search. This avoids simulating rotations and works in linear time. 🔗 LeetCode – Rotate String: https://leetcode.com/problems/rotate-string/description/ 🔗 Companion Reading (Step-by-step with code): https://codeanddebug.in/blog/rotate-string/ 📄 FULL Playlist Sheet (All Videos in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll Free: Master Python DSA Course https://codeanddebug.in/course/master-dsa-with-leetcode 🚀 Advance Python DSA for FAANG (Zero to Hero Course) https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
