and red circles are the most important. A new element gets inserted between one with a higher or equal priority and another one with a lower priority. This rule resembles theinsertion sortalgorithm, which happens to bestable, as elements with the same priority never swap their initial places....
33. How to implement a binary search algorithm in Python? View Answer Hide Answer A binary search algorithm in Python is implemented by repeatedly dividing the sorted list in half until the desired element is found or the whole list is exhausted. To begin with, define three pointers: `low...

In this tutorial, you won’t be implementing any graph traversal algorithms, such as the depth-first search (DFS), breadth-first search (BFS), or Dijkstra’s algorithm for finding the shortest path. Instead, you’ll leverage the excellent NetworkX library, which already implements these and mo...
Subcommands: You can create subcommands to organize and extend the functionality of your program. Subcommands are like mini-programs within your main script. Argument Validation: argparse provides built-in validation for arguments, so you can enforce rules on the values provided by the user. ...
We implement an advanced node class in Python to manage connections Graphs are non-linear structures representing complex relationship Our node class handles dynamic connections efficiently Supports efficient insertion and deletion of connections Graph traversal methods like DFS and BFS return connected nodes...
• Write a program to build a binary search tree using the input keys from the input trees in task 2 • Input file format, the same as task 1 & 2 • Output: • Yes, the tree is already BST or • No, the input tree is not BST, and we re-build it as a BST ...
Some python people avoid using deque for their BFS by doing something like: q = [src] seen = [0] * N seen[src] = 1 for u in q: for v in graph[u]: if not seen[v]: q.append(v) seen[v] = 1 which translates to the following in c++: vector<int> q = {src}; vector<int...
