🔥
Dijkstra Algorithm →
Dijkstra's algorithm uses a priority queue to repeatedly extract the closest unvisited vertex; with a binary heap this yields O((V+E) log V) performance.
🔥
Minimum Spanning Tree →
Prim's MST implementations use a min-priority queue to maintain the frontier and extract the next lightest edge in O(log V), yielding O(E log V) time; without it, typical implementations degrade to O(V^2).
