WebBy now, Dijkstra’s algorithm usually refers to the source-to-all variant, since it also has the same runtime.) (2) What is the running time of Dijkstra’s algorithm using min-heap (aka priority queue) data structure? (Don’t worry about the Fibonacci heap implementation or running time using it.) WebWhen I implement heapsort using a min-heap it sorts the array from largest to smallest. Is this the desired output for a heapsort using min-heap ? It seems redundant to sort again …
