What Is Priority Queue? | DSA in 30 Seconds
A priority queue is a data structure where elements are removed based on priority, not insertion order. Higher-priority elements are served first, commonly implemented using a heap. Used in CPU scheduling, Dijkstra’s algorithm, task scheduling, and interview problems.

Code.hub on Instagram: "Dijkstra’s Algorithm finds the shortest path from a starting node to all other nodes in a weighted graph. It’s used in GPS, network routing, and AI pathfinding. How It Works: 1) Initialize: Set start node distance = 0, others = ∞. Use a priority queue. 2) Process Nodes: Pick the node with the smallest distance, update neighbors if shorter paths are found. 3) Mark Visited: Mark nodes as visited; don’t revisit. 4) Repeat: Continue until all nodes are visited or target is re
