Pre lesson 1

Content

Introduction to Data Structures

• What is an Algorithm
• Why Data Structures
• Stack problem: Evaluate a fully bracketed mathematical expression ((a+b)*c)
• Introduction to Linked List

Lesson 2 : Linked List, Sorting Algorithms and Algorithm complexities

Pre-Lesson

Pre lesson 2

Content

• Introduction to Doubly Linked List
• Insertion sort : O(n2)
• Linear search in a List (O(n))
• Binary search in a sorted list (O(log(n)))
• Linked List Problem : Find if the Linked List has all unique time

Lesson 3 : Trees, Graphs, Recursive Algorithms

Pre-Lesson

• Study and implement selection sort
• Analyze the complexity of a given algorithm and improve it
• Linked List problem: Reverse the linked list

Content

• Reverse the linked list with recursion
• Introduction to trees: Binary tree, Binary Search Tree
• Tree Traversals: In-Order, Post-Order and Pre-Order
• Tree Problem: Find the depth of the tree
• Introduction to Graphs : Data structures for graph

Homework

• Post-Order traversal without recursion (use Stacks)
• Level-wise traversal without recursion (use Queues)
