Problem Statement

Write a C program to split a circular 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

Use slow and fast pointers to find the midpoint of the circular list, split it into two circular lists, and print both.

Starter Code

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

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

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here to split circular 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
