Program Plan Intro

Binary tree:

  • It is a tree data structure which comes under hierarchical data structure.
  • It is made of nodes that have a left child, right child and a data element.

Tree traversal:

  • There are 3 common methods
    • Inorder traversal
    • Preorder traversal
    • Postorder traversal
  • In inorder traversal, the left subtree is encountered first, then data node and then the right subtree.
  • In preorder traversal, the data node is encountered first, then left subtree and then the right subtree.
  • In postorder traversal, the left subtree is encountered first, then right subtree and then the data node.

Algorithm for Postorder traversal:

  • Traverse through the leftmost subtree and then print the element.
  • Ttraverse the rightmost subtree and then print the element.
  • At last visit and print the root node.

Draw a system/level-0 diagram for this scenario: You are developing a new customer relationship management system for the BEC store, which rents out movies to customers. Customers will provide comments on new products, and request rental extensions and new products, each of which will be stored into the system and used by the manager for purchasing movies, extra copies, etc. Each month, one employee of BEC will select their favorite movie pick of that week, which will be stored in the system. The actual inventory information will be stored in the Entertainment Tracker system, and would be retrieved by this new system as and when necessary. Example of what a level-0 diagram looks like is attached.
