Problem Statement

Write a C program to split a doubly linked list into two halves and print both halves separately.

Input Format

First line contains n. Second line contains n elements.

Output Format

First line: elements of the first half. Second line: elements of the second half.

Constraints

2 <= n <= 50

Sample Input

5
10 20 30 40 50

Sample Output

10 20 30
40 50

Explanation

Locate the middle node of the doubly linked list, break the links between the halves, and print both lists.

Starter Code

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

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

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here to split doubly linked list
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
