Question

Consider the function f defined below. ``` struct item l int data; struct item * next; l/ int f(struct item *p) i return ( (p == NULL) 11 (p->next == nULL) || ({ p->-data <= p->next->data) $$\$ $ $$ f(p->next)) ); l ``` For a given linked list p, the function $f$ returns 1 if and only if (GATE CS 2003) A. the list is empty or has exactly one element B. the elements in the list are sorted in non-decreasing order of data value C. the elements in the list are sorted in non-increasing order of data value D. not all elements in the list have the same data value.

   Consider the function f defined below.
```
struct item
l
    int data;
    struct item * next;
l/
int f(struct item *p)
i
    return (
        (p == NULL) 11
        (p->next == nULL) ||
        ({ p->-data <= p->next->data) $$\$ $ $$ f(p->next))
    );
l
```

For a given linked list p, the function $f$ returns 1 if and only if (GATE CS 2003)
A. the list is empty or has exactly one element
B. the elements in the list are sorted in non-decreasing order of data value
C. the elements in the list are sorted in non-increasing order of data value
D. not all elements in the list have the same data value.

Step 1

Step 2: Let's understand each condition: - `(p == NULL)`: Returns true if the list is empty - `(p->next == NULL)`: Returns true if the list has only one element - `((p->data <= p->next->data) && f(p->next))`: Returns true if the current element's data is less Show more…
