Lesson 11 Homework 4.5: Lesson 11 Homework 4.5 Answer Key

Lesson 11 Homework 4.5 is a crucial assignment designed to assess students’ understanding of key concepts related to data structures and algorithms. This homework delves into the implementation and analysis of fundamental data structures such as stacks, queues, and linked lists.

Key Concepts

• Stack implementation using arrays
• Queue implementation using linked lists
• Linked list implementation and operations
• Time and space complexity analysis

Steps Involved

1. Implement a stack using an array.
2. Implement a queue using a linked list.
3. Implement a linked list and demonstrate its operations.
4. Analyze the time and space complexity of the implemented data structures.

Answer Key

Stack Implementation Using Arrays

The stack implementation using an array should include the following methods:

• push(item): Inserts an item onto the top of the stack.
• pop(): Removes and returns the item at the top of the stack.
• peek(): Returns the item at the top of the stack without removing it.
• isEmpty(): Checks if the stack is empty.

Queue Implementation Using Linked Lists, Lesson 11 homework 4.5 answer key

The queue implementation using a linked list should include the following methods:

• enqueue(item): Inserts an item into the rear of the queue.
• dequeue(): Removes and returns the item at the front of the queue.
• peek(): Returns the item at the front of the queue without removing it.
• isEmpty(): Checks if the queue is empty.

Linked List Implementation

The linked list implementation should include the following operations:

• insert(item, index): Inserts an item at the specified index in the linked list.
• delete(index): Deletes the item at the specified index from the linked list.
• get(index): Returns the item at the specified index in the linked list.
• size(): Returns the number of items in the linked list.

Time and Space Complexity Analysis

The homework requires students to analyze the time and space complexity of the implemented data structures. This analysis should include:

• Time complexity of each operation (push, pop, enqueue, dequeue, insert, delete, get, size)
• Space complexity of each data structure
