137 views int find (struct node * first, int n)
{
while (first data ! = n)
first = first — next;
if (first data = = n)
return(1);
else
return (-1);


in the above code segment if the value of 'n' is 5, then the function return 1, but if the value of 'n' is 9, then what does it do ? in DS | 137 views

goes to infinite loop ???

This is the code.

#include<stdio.h>
#include<stdlib.h>

struct Node
{
int data;
struct Node *next;
};

int find (struct Node* first, int n)
{
while (first->data != n)
first = first->next;
if (first->data == n)
return(1);
else
return (-1);
}

void push(struct Node **head_ref, int data)
{
struct Node *ptr1 = (struct Node *)malloc(sizeof(struct Node));
ptr1->data = data;

{
temp = temp->next;
temp->next = ptr1;
}
else
ptr1->next = ptr1;

}

{
{
do
{
printf("%d ", temp->data);
temp = temp->next;
}
}
}

int main()
{

return 0;
} 

Check this out.

from the image, we have to understand that it is a circular linked list.

So, Due to circular linked list and given code, if you are searching a element which is not present in the list, then it will lead to INFINITE LOOP

Ans will be D)

na?

because iff it is not found, then will go to infinite loop

already questioner supplies the value 9 to search ===> option C is correct

oh, I have not seen

thanks

It is not cased that it always will go in infinite loop.it also depend on the implementation of the algorithm.But here it will go in the infinite loop.

@kumar.dilip brother, that's why i commented as
