Given a linked list of **N** nodes. The task is to check if the the linked list has a loop. Linked list can contain self loop.

**Example 1:**

Input:N = 3 value[] = {1,3,4} x = 2Output:TrueExplanation:In above test case N = 3. The linked list with nodes N = 3 is given. Then value of x=2 is given which means last node is connected with xth node of linked list. Therefore, there exists a loop.

**Example 2:**

**Input:
**N = 4
value[] = {1,8,3,4}
x = 0
**Output: **False**
Explanation: **For N = 4 ,x = 0 means
then lastNode->next = NULL, then
the Linked list does not contains
any loop.

**Your Task:**

The task is to complete the function **detectloop**() which contains reference to the head as only argument. This function should return 1 if linked list contains loop, else return 0.

**Expected Time Complexity:** O(N)

**Expected Auxiliary Space:** O(1)

**Constraints:**

1 <= N <= 10^{4}

1 <= Data on Node <= 10^{3}
