Class 13: Merge Sort
project: Puzzle Party – A giant messy puzzle feels impossible at first, so we break it into smaller, friendly pieces. Each piece gets solved easily, and then everything snaps back together into one beautiful, perfectly ordered picture.

Class 14: Quick Sort
project: Team Captain Game – One captain stands in the middle and quickly sends players left or right based on simple rules. Suddenly, order appears almost magically, and we see how smart dividing can beat slow sorting.

Class 15: Counting Sort
project: Candy Factory Counter – Instead of comparing candies one by one, we run a smart candy factory that counts how many of each type exists. With one clever pass, everything gets organized faster than you’d expect.

Class 16: Radix Sort
project: Jersey Number Machine – Jerseys go through a magical scanning machine that checks one digit at a time. From chaos to perfect order, numbers line up smoothly as if the machine knows exactly what it’s doing.

Class 17: Binary Trees Part 1
project: Family Kingdom Builder – We design a royal family kingdom where every parent, child, and grandchild has a clear position. The structure stays balanced and organized, no matter how big the family grows.

Class 18: Binary Trees Part 2
project: Choose-Your-Own Adventure – Every decision creates a new branch in the story. Go left, go right, and watch how choices build a whole world of possibilities without ever getting lost.

Class 19: Binary Trees Part 3
project: Treasure Map Explorer – We explore every branch of a treasure map carefully, making sure no hidden gold is missed. Each path matters, and smart exploration reveals everything.

Class 20: Graphs Part 1
project: City Road Designer – We build a massive city where places are connected by roads, bridges, and shortcuts. The challenge is making sure every location can be reached without confusion.

Class 21: Graphs Part 2
project: Friend Network Detective – Friendships form a giant web, and we investigate who’s connected to whom. One connection leads to another, revealing hidden relationships and surprising links.

Class 22: Graphs Part 3
project: Maze Escape Master – Trapped inside a complex maze, we explore paths, avoid dead ends, and learn how smart exploration helps us escape faster than random guessing.

Class 23: Greedy Algorithms
project: Ice-Cream Budget Boss – Standing in front of an ice-cream shop with limited money, we make the smartest choice at every step. Each decision feels small, but together they lead to the biggest reward.

Class 24: Euclidean Algorithm
project: Chocolate Fairness Judge – A pile of chocolates needs to be divided perfectly between friends. Using clever repeated steps, we guarantee fairness without breaking any rules.

Class 25: Dynamic Programming Part 1
project: Superhero Energy Saver – Every solved challenge becomes a stored superpower. Instead of fighting the same battle again, we reuse our strength and save energy.

Class 26: Dynamic Programming Part 2
project: Level-Up Strategy Game – As the game progresses, earlier wins make future levels easier. Smart memory turns tough challenges into manageable ones.

Class 27: Dynamic Programming Part 3
project: Smart Vacation Planner – Planning trips across many cities sounds overwhelming, but with smart reuse of earlier plans, the perfect vacation comes together effortlessly.

Class 28: Memoization
project: Homework Memory Vault – Once a problem is solved, it gets locked safely inside a memory vault. Next time it appears, the answer is ready instantly.

Class 29: Tabulation
project: Scoreboard Builder – We build a scoreboard row by row, watching answers slowly appear until the full solution stands clearly in front of us.

Class 30: 0/1 Knapsack Problem
project: School Bag Packing Challenge – With limited space in a school bag, every item matters. We choose only the most valuable combination without exceeding the limit.

project: Delivery Hero Route Planner – A delivery hero must visit every house exactly once and return home using the shortest route possible. Every turn matters.

Class 33: Advanced Searching and Sorting
project: Library Speed Finder – Imagine walking into a gigantic library where thousands of books are stacked everywhere. Finding one book the old way would take forever, so we turn this messy space into a super-smart library.

Class 34: Trees and Graphs Together
project: Smart City – We design a living, breathing city from the ground up. Buildings grow like family trees, roads connect places like a giant web, and the challenge is to make sure the city stays connected, efficient, and happy as it grows bigger and more complex.

Class 35: Time and Space Optimization
project: Game Booster Lab – Step into a secret lab where games feel slow, heavy, and laggy. The mission is not to add new features, but to make everything run smoother using smarter thinking. We trim unnecessary steps, reuse space wisely, and watch the same game suddenly feel faster and cleaner without changing how it looks.

Class 36: Real-World Algorithm Design
project: Traffic Signal Brain – Picture a busy city intersection where traffic never seems to stop. Instead of fixed timers, we give traffic lights a brain. They watch the flow, make decisions, and adjust themselves to keep vehicles moving smoothly. One smart rule at a time, chaos turns into calm.

Class 37: Strategy Battle Arena
project: Brain Strategy Showdown – Enter an arena where different problem-solving styles compete head-to-head. Some rush in fast, some plan carefully, and others adapt along the way. We test these strategies under pressure and discover why the way you think can completely change the outcome.
