In this article, we learned about using the Python heapq module and saw how we could use the min-heap property to sort our unordered list. References Python Documentationon the heapq module Vijaykrishna Ram Articles: 102 PreviousPostHow to Rename a File/Directory in Python?

Solution:Python,Cruntime: 16857 μs This was another grid traversal problem. I initially used BFS but then opted to add a priority queue and useDijkstra’s algorithmfor better performance. Within the Python version, I found that treating a standard list as a priority queue (usingheapqmethods)...
Write a Python program that merges multiple sorted inputs into a single sorted iterator (over the sorted values) using the heap queue algorithm. Sample Solution: Python Code: importheapq num1=[25,24,15,4,5,29,110]num2=[19,20,11,56,25,233,154]num3=[24,26,54,48]num1=sorted(num1...
