Basic Data Structures 📝

1. Arrays: A collection of elements of the same data type.
2. Linked Lists: A collection of data elements, each linked to the next in a sequential order.
3. Stacks: A Last-In-First-Out (LIFO) data structure.
4. Queues: A First-In-First-Out (FIFO) data structure.
5. Trees: A hierarchical data structure consisting of nodes and edges.
6. Graphs: A collection of nodes (vertices) connected by edges.

Basic Algorithms 📝

1. Searching Algorithms: Used to find the location of an element in a data structure.
   • Linear Search
   • Binary Search
2. Sorting Algorithms: Used to rearrange the elements of a data structure.
   • Bubble Sort
   • Selection Sort
   • Merge Sort
   • Quick Sort

Solving Problems on AtCoder 💡

1. Understand the Problem: Read the problem statement carefully and identify the problem type.
2. Plan Your Approach: Break down the problem into smaller, manageable sub-problems.
3. Write the Code: Implement your solution using appropriate data structures and algorithms.
4. Test Your Code: Run your code on AtCoder and ensure it passes all test cases.
