struct node *l_occur (struct node *t, int val){
   struct node *res=NULL;
   struct node* trav=t;
   //iterating the list untill we reach the NULL
  
   // storing the node which has the val
   while(trav!=NULL){
       if(trav->data==val)
           res=trav;
   }
   //returning the result
   return res;

}

    A linked list of integers is built using the following struct: struct node {   int data;   struct node *next; }; Define a function named max that returns the maximum integer in a list. The function takes one arguments, a pointer to the head of the list. The function returns an integer, which is the maximum value. If the list is empty, return zero. NOTE: You know nothing about the values in the list. They could all be negative!
