Output
Good Mr John, you are 21 years old
Create a program that will convert the input inch(es) into its equivalent centimeters. One inch is equivalent to 2.54cms. Then display the result.
Even Out
by CodeChum Admin
You know, I was lying when I said the last time that numbers associated with 3 are my favorite, because the one I actually like the most in the world are even numbers! But to make things harder for you, you have to pick the even numbers from a range of two given numbers. Ha!
Now, let's try this one more time!
Instructions:
Input two integers in one line, separated by a space. The first integer shall represent the starting point, and the other, the ending point.
Print out all even numbers that are within the range of the starting and ending point (inclusive or including the ending point).
Input
A line containing two integers separated by a space.
5·10
Output
A line containing integers separated by a space.

Factorials
by CodeChum Admin
For those of you who may not now, a factorial is a product of multiplying from 1 until the number. Now, you must make a program that will accept an integer and then print out its factorial using loops.
Are you up for this task?
Instructions:
Input a positive integer.
Using a for() loop, generate the factorial value of the integer and print out the result.
Tip #1: Factorials work like this: Factorial of 5 = 1 * 2 * 3 * 4 * 5
Tip #2: There's a special case in factorials. The factorial of 0 is 1.
Input
A line containing an integer.
5
Output
A line containing an integer.

- LOOPS&CONDITIONS: Create a program that takes in two numbers and then calculate the sum of all even numbers in between the two numbers. The program should also calculate the products of all the odd numbers between the provided numbers.
Sample run 1:
Enter two numbers: 2 8
Output:
Even numbers: 2 4 6 8
Odd numbers: 3 5 7
Sum of even numbers = 20
Product of odd numbers = 105
Correct the code:-
public class DLL {
private Node start;
private Node end;
int count;
public DLL() {
start = end = null;
count=0;
}
public void insertAtstrat (Data d) {
if (count == 0) {
Node tn = new Node(d,null,null);
start = end = tn;
}
else {
Node tn = new Node (d,start,null);
start.prev = tn;
start (tn);
count++;
}
}
public void insertAtend (Data d) {
if (count == 0) {
insertAtend(d);
}
else {
Node tn = new Node(d,null,end);
end.next = tn;
end = tn;
count++;
}
public void insertAt(Data d, index i) {
if (count ==0 || index == 0);
insertAtstart(d);
else if (i >= count);
insertAtend(d);
else {
Node temp = start;
for (a = 1);
temp = temp.Node;
Node tn = new Node(d, temp.next, temp);
temp.next = tn;
temp = tn.next;
temp.prev = tn;
}
}
}
}
public class Node {
Data d;
Node next;
Node prev;
public Node (Data d,Node n,Node p) {
d = new Data();
next = n;
prev = p;
}
