Hard Doubly Linked List: Advanced PRO

🔒 Login to Unlock

Problem Statement

Write a C program to check whether a doubly linked list is a palindrome (print 1 if true, 0 otherwise).

Input Format

First line contains n. Second line contains n elements.

Output Format

Print 1 if palindrome, else 0.

Constraints

1 <= n <= 100

Sample Input

5
1 2 3 2 1

Sample Output

Explanation

Use two pointers, one starting from head and one from tail, moving towards each other to compare node data values.

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 check if doubly linked list is a palindrome
    }
    return 0;
}
