Creative Ways to Write Names in the Sand

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

AI | Technology on Instagram: "Chinese scientists have developed a smart swarm algorithm that allows multiple drones to work together as a coordinated team. By sharing data in real time, the drones can balance forces, synchronize movement, and collectively lift heavy loads that a single drone could not manage. This swarm intelligence also helps drones navigate complex environments, avoid obstacles, and adapt on the fly. Such technology has strong potential for emergency rescues, disaster relief,
