Send Feedback
You have been given a singly linked list of integers. Write a function that returns the index/position of integer data denoted by 'N' (if it exists). Return -1 otherwise.
Note :
Assume that the Indexing for the singly linked list always starts from 0.
Sample Input 1 :
2
3 4 5 2 6 1 9 -1
5
10 20 30 40 50 60 70 -1
6
Sample Output 1 :
2
-1
Explanation for Sample Output 1:
In test case 1, 'N' = 5 appears at position 2 (0-based indexing) in the given linked list.
In test case 2, we can see that 'N' = 6 is not present in the given linked list.
Sample Input 2 :
2
1 -1
2
3 4 5 2 6 1 9 -1
6
Sample Output 2 :
-1
4
Explanation for Sample Output 2:
In test case 1, we can see that 'N' = 2 is not present in the given linked list.
In test case 2, 'N' = 6 appears at position 4 (0-based indexing) in the given linked list.
