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

Gyani Kumari on Instagram: "Can you solve this without a HashMap? 🤔 Problem: Find the element that appears more than N/2 times. Challenge: Space Complexity must be O(1). Meet: Moore’s Voting Algorithm. The concept is simple: Cancellation. If you have a Majority, your count will survive even if every non-majority element tries to cancel you out. Candidate == Current 👉 Increase Count Candidate != Current 👉 Decrease Count If Count drops to 0, we pick a new candidate. The one left standing at the
