Array Traversal
EasyVisit and process each element in the array sequentially.
O(n)Insertion
EasyInsert element at specific position, shifting elements as needed.
O(n)Deletion
EasyRemove element from array and shift remaining elements.
O(n)Search Operations
MediumFind element using linear or binary search techniques.
O(n) / O(log n)Update/Modify
EasyUpdate value at specific index with constant time access.
O(1)Array Rotation
MediumRotate array elements left or right by k positions.
O(n)Array Reversal
EasyReverse the order of elements in the array.
O(n)Merge Arrays
MediumCombine two arrays into one maintaining order.
O(m + n)Subarray Operations
MediumFind max sum, sliding window, and subarray problems.
O(n)Two Pointer Technique
MediumUse two pointers for efficient array manipulation.
O(n)Each operation includes interactive visualization, code implementation, and complexity analysis

Array Characteristics & Notes
*Amortized: Average over sequence of operations
In-place: Modifies original array, O(1) extra space
Contiguous: Elements stored in adjacent memory locations
Random Access: O(1) access to any index
Cache-friendly: Sequential access patterns
Fixed Size: Static arrays cannot grow dynamically
