Use a stack to simulate the recursive inorder traversal process
Create an empty stack to store nodes
Start with the root node and push it onto the stack
While the stack is not empty, keep traversing left and pushing nodes onto the stack
Once you reach a leaf node, pop it from the stack, print its value, and move to its right child
Repeat the process until all nodes have been visited

Collections in programming refer to data structures that allow you to store and manipulate groups of objects.
Collections provide a way to organize and manage data efficiently
