Congratulations on implementing a breadth-first search algorithm using Python!

Let’s go over the steps taken to create a breadth-first search function:

• Before starting the search, define the tree’s root node as well as a value to search for.
• Initialize a frontier queue, which holds a path for each node to search
• Loop through the frontier queue to check if the node value matches the value we are searching for.
• Continue the search by adding child nodes to the frontier until the goal has been found, or the tree has been completely searched.
