Medium Singly Linked List: Basics

Solve in Playground →

Problem Statement

Write a C program to format and print a singly linked list with structural arrows (e.g., 1 -> 2 -> 3 -> NULL).

Input Format

First line contains n. Second line contains n integers.

Output Format

Print the linked list format ending with NULL.

Constraints

1 <= n <= 50

Sample Input

3
10 20 30

Sample Output

10 -> 20 -> 30 -> NULL

Explanation

Traverse the linked list and print each node's data followed by '->', terminating with 'NULL'.

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 build and print with arrow format
    }
    return 0;
}
