Question

Write C++ code to:

A linked list version of any_different(), called like this:

bool any_different() const

(3) A RECURSIVE list member function of integer_linked_list that returns true if all elements in the list are equal to a passed in value.

bool all_equal_to(int val) const. // calls helper
bool all_equal_to_helper(snode* no, int val) const. // recursive
e.g., if the list had 10-->20-->30-->40-->50-->nullptr
and was passed val=30, it would return false
but if the list had 20-->20-->20-->20-->20-->10,
and was passed val=40, it would return false,
bur if it was passed val=20, it would return true

Answer 1

A RECURSIVE list member function of integer_linked_list that returns true if all elements in the list are equal to a passed in value.
Here ,head is the first node of integer_linked_list

bool all_equal_to(int val) const{
   return all_equal_to_helper(head,val);
}
bool all_equal_to_helper(snode* no, int val) const{
   if(no == NULL)return true;
   if(no->data != val)return false;
   return all_equal_to_helper(no->next,val);
}
