Blocking statements halt program execution until the statement is complete, while nonblocking statements allow the program to continue executing while waiting for the statement to complete.
Blocking statements can cause the program to hang or become unresponsive if the statement takes a long time to complete.
Nonblocking statements are often used in asynchronous programming to allow multiple tasks to be executed simultan...

The width of a tree is the maximum number of nodes at any level in the tree.
To calculate the width of a tree, we can perform a level order traversal and keep track of the maximum number of nodes at any level.
We can use a queue data structure to perform the level order traversal.
At each level, we count the number of nodes in the queue and update the maximum width if necessary.
