# Print in Reverse

### Problem Statement :

```Given a pointer to the head of a singly-linked list, print each data value from the reversed list. If the given list is empty, do not print anything.

Example

Print the following:
3
2
1

Function Description:

Complete the reversePrint function in the editor below.

reversePrint has the following parameters:

Prints

The data values of each node in the reversed list.

Input Format:

The first line of input contains t, the number of test cases.

The input of each test case is as follows:
1. The first line contains an integer n, the number of elements in the list.
2. Each of the next n lines contains a data element for a list node.

Constraints:
1.   1<=n<=1000
2.   1<=list[i]<=1000```

### Solution :

```                            ```Solution in C :

In C:

//the following fuction is all that is needed to complete the
//challenge in hackerrank platform.

while(current!=NULL)
{   next=current->next;
current->next=prev;
prev=current;
current=next;

}
while(temp!=NULL)
{
printf("%d\n",temp->data);
temp=temp->next;
}

}

In C++:

//the following fuction is all that is needed to complete the
//challenge in hackerrank platform.

{
// This is a "method-only" submission.
// You only need to complete this method.
{
}

}

In Java:

//the following method is all that is needed to complete the
//challenge in hackerrank platform.

}

}

In Python 3 :

//the following method is all that is needed to complete the
//challenge in hackerrank platform.

return
```

## Insert a Node at the Tail of a Linked List

You are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty. Input Format: You have to complete the SinglyLink

Given a pointer to the head of a linked list, insert a new node before the head. The next value in the new node should point to head and the data value should be replaced with a given value. Return a reference to the new head of the list. The head pointer given may be null meaning that the initial list is empty. Function Description: Complete the function insertNodeAtHead in the editor below

## Insert a node at a specific position in a linked list

Given the pointer to the head node of a linked list and an integer to insert at a certain position, create a new node with the given integer as its data attribute, insert this node at the desired position and return the head node. A position of 0 indicates head, a position of 1 indicates one node away from the head and so on. The head pointer given may be null meaning that the initial list is e

## Delete a Node

Delete the node at a given position in a linked list and return a reference to the head node. The head is at position 0. The list may be empty after you delete the node. In that case, return a null value. Example: list=0->1->2->3 position=2 After removing the node at position 2, list'= 0->1->-3. Function Description: Complete the deleteNode function in the editor below. deleteNo

## Print in Reverse

Given a pointer to the head of a singly-linked list, print each data value from the reversed list. If the given list is empty, do not print anything. Example head* refers to the linked list with data values 1->2->3->Null Print the following: 3 2 1 Function Description: Complete the reversePrint function in the editor below. reversePrint has the following parameters: Sing
