As your shoulders rotate, feel your navel gently drawing back toward your low spine, with your entire back “filling out” behind you through the preparation and the turn. ✅ 𝐒𝐢𝐦

Gyani Kumari on Instagram: "Rotate Array in O(1) Space? 🤯 Agar array ko rotate karna hai bina extra memory use kiye, toh Reversal Algorithm use karo! The Pro Way: 3 Reverse Calls. Only O(N) Time and O(1) Space. 🔥 code: void rotate(int a[], int n, int k) { k = k % n; // Handle cases where k > n reverse(a, a + n); reverse(a, a + k); reverse(a + k, a + n); } Simple, Clean, and Optimized. Share this with a friend who writes long code for simple problems! 😂 #leetcode #dailycoding #geeksforgeeks #c
