2. Given a 2-D char array, with random alphabets, find the word “INTUIT”, s/t “N” lies in the neighborhood of I, T lies in the neighborhood of N, and so on. Neighborhood meaning any of the eight squares around the middle square. Approach and code using recursion. 
3. Linked List: Pairwise reverse the linked List, eg : 1->2->3->4->NULL to 2->1->4->3->NULL. Code with proper syntax. Dry Run
