How can I sort a linked list in C++?

You can sort a linked list in C++ using various algorithms like Merge Sort or Quick Sort. Which one would you like to know about?

Can you explain how to implement Merge Sort for a linked list?

Sure! Merge Sort is a divide-and-conquer algorithm. First, you split the linked list into two halves, then recursively sort each half, and finally merge the sorted halves. Would you like a code example?

Yes, please provide a code example for Merge Sort.

Here's a simple implementation of Merge Sort for a linked list in C++:

struct Node {
    int data;
    Node* next;
};

Node* merge(Node* left, Node* right) {
    // Merging logic here
}

Node* mergeSort(Node* head) {
    // Splitting and sorting logic here
}

Let me know if you need more details!

What are the time and space complexities of Merge Sort?

The time complexity of Merge Sort is O(n log n) and the space complexity is O(n) due to the temporary arrays used for merging.
