Given a linked list of size **N**. The task is to complete the function **countNodesinLoop() **that checks whether a given Linked List contains a **loop or not **and if the **loop **is present then** return the count of nodes** in a loop or else **return 0. C **is the position of the node to which the last node is connected. If it is 0 then no loop.

**Example 1:**

**Input:
**N = 10
value[]={25,14,19,33,10,21,39,90,58,45}
C = 4
**Output: **7**
Explanation: **The loop is 45->33. So
length of loop is 33->*10*->21->39->
90->58->*45* = **7. **The number 33 is
connected to the last node to form the
loop because according to the input the
4^{th} node from the beginning(1 based
index) will be connected to the last
node for the loop.

**Example 2:**

**Input:
**N = 2
value[] = {1,0}
C = 1
**Output: **2**
Explanation: **The length of the loop
is 2.

**Your Task:**

The task is to complete the function **countNodesinLoop**() which contains the only argument as reference to head of** linked list **and return the lenght of the loop ( 0 if there is no loop).

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

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

**Constraints:**

1 <= N <= 500

0 <= C <= N-1
