FlexArray

FlexArray is a Python library that provides an array-like structure with dynamic memory allocation features similar to C's malloc, realloc, and free.

Installation

You can install the package via pip:

pip install flexarray

Usage

Implementing Array with flexarray

from flexarray.array import Array

# Create an array with initial size 3
arr = Array(3)
arr[0] = 10
arr[1] = 20
print(arr)  # Array([10, 20, None])

# Automatic dynamic resizing
arr[5] = 50
print(arr)  # Array([10, 20, None, None, None, 50])

# Malloc: Allocate memory dynamically
arr.malloc(5)
print(arr)  # Array([None, None, None, None, None])

# Realloc: Resize the array
arr.realloc(10)
print(arr)  # Array([None, None, None, None, None, None, None, None, None, None])

# Free: Deallocate memory
arr.free()
print(arr)  # Array([])

Using Mathematics and Sorting on FlexArray

from flexarray.array import Array
from flexarray.mathematics import (
    SumOfElements, AverageOfElements, MaxElement, MinElement, 
    ProductOfElements, MedianOfElements, ModeOfElements
)
from flexarray.sorting import BubbleSort, SelectionSort, InsertionSort

# Step 1: Create a FlexArray with initial elements
arr = Array(6)
arr[0] = 10
arr[1] = 20
arr[2] = 30
arr[3] = 40
arr[4] = 50
arr[5] = 60

# Step 2: Perform mathematical operations
print("Sum of elements:", SumOfElements(arr))  # Output: 210
print("Average of elements:", AverageOfElements(arr))  # Output: 35.0
print("Maximum element:", MaxElement(arr))  # Output: 60
print("Minimum element:", MinElement(arr))  # Output: 10
print("Product of elements:", ProductOfElements(arr))  # Output: 720000000
print("Median of elements:", MedianOfElements(arr))  # Output: 35.0
print("Mode of elements:", ModeOfElements(arr))  # Output: None (since no repeating elements)

# Step 3: Sorting FlexArray using different algorithms
# Bubble Sort
BubbleSort(arr)
print("Array after Bubble Sort:", arr)

# Selection Sort
arr.realloc(6)  # Reset array for demonstration
arr[0], arr[1], arr[2], arr[3], arr[4], arr[5] = 50, 40, 30, 20, 10, 60  # Unsorted
SelectionSort(arr)
print("Array after Selection Sort:", arr)

# Insertion Sort
arr.realloc(6)  # Reset array again
arr[0], arr[1], arr[2], arr[3], arr[4], arr[5] = 60, 50, 40, 30, 20, 10  # Unsorted
InsertionSort(arr)
print("Array after Insertion Sort:", arr)
