Month 4 of 10
Data Structures & Algorithms
Think algorithmically. Solve any problem. Ace any interview.
About This Month
What you'll experience in Month 4
Data structures and algorithms are the backbone of computer science and the subject of every technical interview at top tech companies. Month 4 builds your problem-solving muscle: you will learn how to choose the right data structure for any problem, analyse time and space complexity, and implement classic algorithms from scratch. By the end, you will be able to approach challenging coding problems with a structured, confident mindset.
What You'll Learn
Concrete skills you'll walk away with after this month
Understand Big-O notation and analyse the complexity of any algorithm
Implement and use arrays, linked lists, stacks, queues, and hash maps
Traverse, search, and modify trees and graphs
Apply classic sorting algorithms: bubble, selection, merge, and quicksort
Use binary search and other efficient search techniques
Solve problems using recursion, dynamic programming, and greedy strategies
Recognise common problem patterns and apply the right algorithm
