Arrays
Definition: Arrays store elements of the same type in contiguous memory, accessed by index.
Characteristics:
Fixed Size: Same type elements. Sequential Access: Indexed. Contiguous Memory: Adjacent storage. Ordered: Indexed from 0 to N-1. Advantages:
Efficient Storage: Contiguous memory. Random Access: Direct via index. Versatility: Various data types. Types:
Single-Dimensional: Linear collection. Multidimensional: Multiple dimensions like 2D, 3D. 2. Key Algorithms
Two Pointers: Use two pointers to navigate arrays from both ends until a condition is met.
Sliding Window: Slide a fixed-size window across the array to find optimal solutions.
Kadane's Algorithm: Traverse the array to find the maximum sum of a contiguous subarray.
3. Multi-Dimensional Arrays
Introduction: Extend arrays into multiple dimensions.
Types:
2D Arrays: Rows and columns. 4. Matrix Traversal
Introduction: Visit matrix elements in specific order.
Techniques:
Column-wise: Top to bottom. Zigzag: Alternate directions. Conclusion: Master arrays and algorithms for optimized problem-solving. Use multi-dimensional arrays and matrix traversal for complex data, essential for competitive programming and real-world applications. For more detailed information, refer to the Notion link:
