Tricky Interview#2

Question:

Write a function that moves the last element to the front in a given Singly Linked List.

 For example:

Input Linked List is 1->2->3->4->5.
Output Linked List 5->1->2->3->4.

Solution:

Move last element to front of a given Linked List

Question:
Write a function that moves the last element to the front in a given Singly Linked List.

 For example:

Input: 1->2->3->4->5

Output: 5->1->2->3->4.



Algorithm:

Traverse the list till the last node. Use two pointers: one to store the address of the last node and other for the address of the second last node. After the end of the loop do the following operations.
i) Make second last as last (secLast->next = NULL).
ii) Set next of last as head (last->next = *head_ref).
iii) Make last as head ( *head_ref = last)



 C Program :

#include<stdio.h>
#include<stdlib.h>
struct Node
{
    int data;
    struct Node *next;
};

void moveToFront(struct Node **head_ref)
{
    /* If linked list is empty, or it contains only one node,
      then nothing needs to be done, simply return */
    if (*head_ref == NULL || (*head_ref)->next == NULL)
        return;

    /* Initialize second last and last pointers */
    struct Node *secLast = NULL;
    struct Node *last = *head_ref;

    /*After this loop secLast contains address of second last
    node and last contains address of last node in Linked List */
    while (last->next != NULL)
    {
        secLast = last;
        last = last->next;
    }

    /* Set the next of second last as NULL */
    secLast->next = NULL;

    /* Set next of last as head node */
    last->next = *head_ref;

    /* Change the head pointer to point to last node now */
    *head_ref = last;
}

/* UTILITY FUNCTIONS */
/* Function to add a node at the begining of Linked List */
void push(struct Node** head_ref, int new_data)
{
    /* allocate node */
    struct Node* new_node =
        (struct Node*) malloc(sizeof(struct Node));

    /* put in the data  */
    new_node->data  = new_data;

    /* link the old list off the new node */
    new_node->next = (*head_ref);

    /* move the head to point to the new node */
    (*head_ref)    = new_node;
}


/* Function to print nodes in a given linked list */
void printList(struct Node *node)
{
    while(node != NULL)
    {
        printf("%d ", node->data);
        node = node->next;
    }
}

int main()
{
    struct Node *start = NULL;

    push(&start, 5);
    push(&start, 4);
    push(&start, 3);
    push(&start, 2);
    push(&start, 1);

    printf("\n Linked list before moving last to the front\n");
    printList(start);

    moveToFront(&start);

    printf("\n Linked list after removing last to the  front\n");
    printList(start);

    return 0;
}


Output:
 Linked list before moving last to the front
1 2 3 4 5
 Linked list after removing last to the front
5 1 2 3 4

Integer Promotions in C

Integer Promotions in C

Some data types like char, short int take less number of bytes than int, these data types are automatically promoted to int or unsigned int when an operation is performed on them. This is called integer promotion. For example, no arithmetic calculation happens on smaller types like char, short and enum. They are first converted to int or unsigned int, and then arithmetic is done on them. If an int can represent all values of the original type, the value is converted to an int. Otherwise, it is converted to an unsigned int.

For example see the following program:

#include <stdio.h>
int main()
{
    char a = 30, b = 40, c = 10;
    char d = (a * b) / c;
    printf ("%d ", d);
    return 0;
}

Output:

120
At first look, the expression (a*b)/c seems to cause arithmetic overflow because signed characters can have values only from -128 to 127 (in most of the C compilers), and the value of subexpression ‘(a*b)’ is 1200 which is greater than 128. But integer promotion happens here in arithmetic done on char types and we get the appropriate result without any overflow.

Generic Storing of Number

Question:
Write a Java program the implements a generic sort method using any of the sorting techniques.

Solution:

public class Students{

   public static <T extends Comparable<T>> void sortingMethod(Number[] i2)   {

    int i,j,n;

    n=i2.length;

    for(i=0;i<n;i++)

     for(j=0;j<n-i-1;j++)

      if(((Comparable<T>) i2[j]).compareTo((T) i2[j+1])>0)

      {

       T temp;

       temp=(T) i2[j];

       i2[j]=i2[j+1];

       i2[j+1]=(Number) temp;

      }

    System.out.println();

    System.out.println("After Sorting The Elements");

    for(Number element: i2)

    System.out.printf("%s, ", element);

   }

   public static void main(String args[])

   {

    Number i[]={3.2,2.5,10.02,7.012,7.06};

    System.out.println("Before Sorting The Elements");

    for(Number element:i)

     System.out.printf("%s, ",element);

    sortingMethod(i);

   }



}





Output:

Before Sorting The Elements

3.2, 2.5, 10.02, 7.012, 7.06, 

After Sorting The Elements

2.5, 3.2, 7.012, 7.06, 10.02,
