1. You are given a singly linked list N nodes.
2. You are also given a key K.
3. You have to write a function that counts the number of occurrences of given key in linked list and returns the count value.
4. display is a utility function which displays the contents of Linked List, feel free to use it for debugging purposes.
5. main takes input from the users and creates the Linked List. You can use display to know its contents.
6. This is a functional problem.
7. You have to complete the frequency function. It takes as input the head of the linked list and K. It should return the count value.
8. Don't change the code of Node, main and display.Input Format
First line takes N, the number of elements in the list. Second line takes input N space separated numbers reperesenting elements of the linked list. Third line takes input K. Input is handled for you.
Output Format
Modified Linked List. Output is handled for you.
Constraints
1 <= N <= 1000
