Array Visualization

Operation Steps

How to Use

Setup: Enter numbers separated by commas or click "Random" to generate an array
Traverse: Click "Traverse" to visit each element sequentially
Search: Enter a value and click "Search" to find its index position
Insert: Enter index and value, then click "Insert" to add a new element
Delete: Enter index and click "Delete" to remove an element
Observe: Watch elements being processed with color-coded visualization
Reset: Click "Reset" to restore the original array and start over

Colors: Orange = Current Element, Green = Found/Success, Blue = New Element, Red = Deleted

Array Concept

Array is a linear data structure that stores elements of the same data type in contiguous memory locations.

Key Characteristics:

Fixed size (in most languages)
Elements accessed by index (0-based)
Homogeneous data (same type)
Random access capability
Contiguous memory allocation

Purpose & Applications

Why use Arrays?

Fast random access to elements O(1)
Memory efficient storage
Cache-friendly due to locality
Simple implementation
Foundation for other data structures

Common Applications:

Storing collections of data
Implementing other data structures
Mathematical computations
Image and signal processing
Database indexing

Time & Space Complexity

Operation	Time Complexity	Space Complexity
Access	O(1)	O(1)
Search	O(n)	O(1)
Insertion	O(n)	O(1)
Deletion	O(n)	O(1)
Traversal	O(n)	O(1)

Strengths & Limitations

Strengths:

Constant time access O(1)
Memory efficient
Cache performance
Simple to understand
Supports random access

Limitations:

Fixed size (static arrays)
Expensive insertion/deletion
Memory waste if not full
No automatic resizing
Homogeneous data only

Array Code Implementation

ALGORITHM ArrayOperations
INPUT: Array A, operations
OUTPUT: Modified array or search results

// Array Declaration
DECLARE Array A[n]

// Traversal
ALGORITHM Traverse(A)
BEGIN
    FOR i = 0 TO length(A) - 1 DO
        PRINT A[i]
    END FOR
END

// Search
ALGORITHM LinearSearch(A, target)
BEGIN
    FOR i = 0 TO length(A) - 1 DO
        IF A[i] = target THEN
            RETURN i
        END IF
    END FOR
    RETURN -1
END

// Insertion
ALGORITHM Insert(A, index, value)
BEGIN
    IF index < 0 OR index > length(A) THEN
        RETURN "Invalid index"
    END IF
    
    FOR i = length(A) DOWN TO index + 1 DO
        A[i] = A[i-1]
    END FOR
    
    A[index] = value
    INCREMENT length(A)
END

// Deletion
ALGORITHM Delete(A, index)
BEGIN
    IF index < 0 OR index >= length(A) THEN
        RETURN "Invalid index"
    END IF
    
    FOR i = index TO length(A) - 2 DO
        A[i] = A[i+1]
    END FOR
    
    DECREMENT length(A)
END
