#Priority Queue

What are Heaps and PriorityQueue ? We use PriorityQueue as Min-Heap and Max-Heap in coding . . . . . . . . . . . . #coding #software #softwaredeveloper #job #fang #google #amazon #development #developer #career #learning #programming #leetcode #codingquestions #googleinterview #microsoftinterview #softwareengineer #amazonjobs #softwaredevelopment #hrinterview #motivation #interview #cs #viral #java #hr #dsa #tcsnqt #algorithm #itsruntym

Priority queue heap insert. To enqueue, we put the new value at the end of the array. Then move it up based on its value compared to its parent. If its value is greater than its parent, it should be relocate to the position with its parent. We call this process bubble up or heap up. The time complexity is O(logn). #computerscience#programmer#coder#priorities

🚀 Master the Queue Data Structure – FIFO in Action! A queue is a linear data structure that follows the FIFO (First In, First Out) principle. Think of it like a waiting line at a store: 🔹 The first person in line gets served first (dequeue). 🔹 New arrivals join at the end (enqueue). 🔍 Queue Operations: ✅ Enqueue(x) – Add an element to the back of the queue. ✅ Dequeue() – Remove the front element. ✅ Front() – View the first element without removing it. ✅ isEmpty() – Check if the queue is empty. 🔥 Where Are Queues Used? ✅ Task Scheduling – CPU scheduling in operating systems. ✅ Printing Jobs – Documents are printed in order. ✅ Breadth-First Search (BFS) – Used in graph traversal. ✅ Messaging Systems – Used in real-time applications like chat apps. ⚡ Types of Queues: 📌 Simple Queue – Basic FIFO queue. 📌 Circular Queue – The last position connects back to the front. 📌 Priority Queue – Elements with higher priority get dequeued first. 📌 Deque (Double-Ended Queue) – Insert and remove from both ends. 💡 Did you know? The word "queue" is the only English word that sounds the same even if you remove all letters after the first "Q"! 🤯 📌 Have a question? Drop it in the comments!

Multilevel Feedback Queue (MLFQ) is a CPU scheduling algorithm that uses multiple queues with different priority levels. Processes start in a high-priority queue and move to lower-priority queues if they use too much CPU time, allowing short tasks to complete quickly while ensuring fairness. Modern operating systems use MLFQ because it efficiently balances responsiveness and CPU utilization, dynamically adjusting priorities to optimize performance for interactive and background processes. #MLFQ #multilevelfeedbackqueue #OS #operatingsystem #cpu #cpuscheduling

A stack is a last-in, first-out (LIFO) data structure, where elements are added and removed from the same end. A queue is a first-in, first-out (FIFO) data structure, where elements are added at the rear and removed from the front. A priority queue is a data structure where elements have assigned priorities, and the element with the highest priority is served before others. It doesn't follow a strict order like stacks or queues. In summary: - Stack: LIFO, elements added and removed from the same end. - Queue: FIFO, elements added at the rear, removed from the front. - Priority Queue: Elements have priorities, highest priority served first. #Stack #LIFO #DataStructure #LastInFirstOut #Programming #Queue #FIFO #DataStructure #FirstInFirstOut #Programming #PriorityQueue #DataStructure #PriorityQueue #Programming #PriorityOrder

Merge K Sorted Lists 🔥 The Interview Trick Most Developers Miss This is one of the most popular Linked List interview problems. At first, merging lists one by one looks easy… But the real challenge is optimizing the solution. The best approach uses: • Min Heap (Priority Queue) • Divide & Conquer Both reduce the complexity to O(N log K) and are commonly asked in coding interviews. If you're preparing for FAANG or product-based companies, this pattern is a must know. Save this reel for your DSA revision.
