my code is not passing one testcase i don’tknow where its wrong.
Here’s my code:
#include
#include
#include
#include
#include
#include
#define lli long long int
#define ll long int
using namespace std;
class node
{
public:
lli data;
node *next;
node(lli d)
{
data = d;
next = NULL;
}
};
void Insertathead(node *&head,lli data)
{
node * n = new node(data);
n->next = head;
head = n;
}
void print(node head)
{
nodetemp = head;
while(temp!=NULL)
{
cout<data<<"->";
temp = temp->next;
}
}
node nTHnode(node&head,int k)
{
node * fast = head;
node * slow = head->next;
int i=1;
while(fast->next!=NULL) // as we don't want to implement last node since its next will be null
{if(i<=k)
{
fast = fast->next;
}
else
{
fast = fast->next;
slow = slow->next;
}
i++;
}
return slow;
}
void insertAtTail(node*&head,lli data){
if(head==NULL){
head = new node(data);
return;
}
node*tail = head;
while(tail->next!=NULL){
tail = tail->next;
}
tail->next = new node(data);
return;
}
int main() {
node * head = NULL; //6,5,4,3,2,1
lli num;
scanf("%lld ",&num);
while(num!=-1)
{
insertAtTail(head,num);
scanf("%lld ",&num);
}
int k;
scanf("\n%d",&k);
node* ans = nTHnode(head,k);
cout<data;
return 0;
}
Please help, TIA!!
