Program Code – Programs C Language: Creating Efficient Solutions

#include <stdio.h>
#include <stdlib.h>

// Function Prototypes
void quickSort(int *arr, int left, int right);
int partition(int *arr, int left, int right);

int main() {
    int *arr;
    int i, numElements;

    // Input: Total number of elements
    printf('Enter the number of elements: ');
    scanf('%d', &numElements);

    // Dynamic memory allocation for array
    arr = (int*)malloc(numElements * sizeof(int));

    // Input: Array elements
    printf('Enter the elements: 
');
    for(i = 0; i < numElements; i++) {
        scanf('%d', &arr[i]);
    }

    // QuickSort function call
    quickSort(arr, 0, numElements - 1);

    // Output: Sorted array
    printf('Sorted Array: 
');
    for(i = 0; i < numElements; i++) {
        printf('%d ', arr[i]);
    }
    
    // Free allocated memory
    free(arr);

    return 0;
}

// QuickSort
void quickSort(int *arr, int left, int right) {
    if (left < right) {
        // Find pivot element such that element(s) on the left are less they are on right
        int pivot = partition(arr, left, right);

        // Recursively sort elements before and after partition
        quickSort(arr, left, pivot - 1);
        quickSort(arr, pivot + 1, right);
    }
}

// Partition function
int partition(int *arr, int left, int right) {
    int pivot = arr[right]; // pivot
    int i = (left - 1); // Index of smaller element

    for (int j = left; j <= right - 1; j++) {
        // If current element is smaller than the pivot
        if (arr[j] < pivot) {
            i++; // increment index of smaller element
            // Swap arr[i] and arr[j]
            int temp = arr[i];
            arr[i] = arr[j];
            arr[j] = temp;
        }
    }
    // Swap arr[i + 1] and arr[right] (or pivot)
    int temp = arr[i + 1];
    arr[i + 1] = arr[right];
    arr[right] = temp;

    return (i + 1); // Return the partitioning index
}

Code Output:

Enter the number of elements: 5
Enter the elements: 
3 1 4 1 5
Sorted Array: 
1 1 3 4 5 

Code Explanation:

This program demonstrates the implementation of the QuickSort algorithm in C, which is a highly efficient sorting algorithm. It’s chosen for its average and worst-case time complexity of O(n log n) and O(n^2), respectively, making it suitable for large datasets.

1. Dynamic Memory Allocation: The program starts by dynamically allocating memory for the array based on the user’s input. This allows for adaptable memory management, ensuring that only the necessary amount of memory is used.
2. QuickSort Logic: The core of this program lies in the quickSort function, which recursively sorts the array. It uses a divide-and-conquer approach, dividing the array into two halves around a pivot element such that the left half contains elements smaller than the pivot and the right half contains elements greater than it.
3. Partitioning: The partition function is where the sorting action happens. It selects a pivot (here, the last element of the array) and rearranges the array so that all elements smaller than the pivot come before it, and all elements greater come after it. It then swaps the pivot to its correct position in the sorted array.
4. Recursion: The quickSort function calls itself recursively for the two halves of the array, each time narrowing down until the base condition is met (when the sub-array has less than or equal to one element), at which point the array is considered sorted.
5. Cleaning Up: At the end, the program frees up the dynamically allocated memory to prevent memory leaks, showcasing good memory management practices.

This program elegantly showcases the power of recursive algorithms and dynamic memory allocation in C for efficient problem-solving. It’s a fine example of combining theoretical algorithmic efficiency with practical memory management.
