@sulekha
your analogy ,i.e., comparing objects to primitives is not correct,
objects do not just hold data,they have some behavior as well.In Object
Oriented Programming language Objects are defined as to reflect a real
world entity. Inheritance is also a feature inspired from the real world.
So a

according to my understanding the super class object have limited function
like for example
Class - animal : methods/behavior : roam() and eat()
and a sub class hippo : method/behavior : roam(),eat() and swim()
so a hippo is a animal then according to the polymorphic property of java

i think its just a logical reason take animal as superclass bird as
subclass ... since we are talking about inheritance it is " is a
relationship " ie bird is a animal not vice versa hence we cannot
implicitly convert to subclass

Hi,
Im new to algorithms, so this might be a simple question for most of you
Lets say there are 5 trucks, each of which can take 100kg load. And they
are filled to some extent randomly.
Let the free quantity be 40kg, 30kg, 20kg, 80kg, 60kg respectively. At any
given time only single load comes.

Can anybody suggest a program on how to "convert a n-ary tree to an
array and reconstruct the tree from the array" in java?

Although there is no pointer concept in java, but still underlying

What you want is to send a copy of your list again recursively.

@Mihir
Just understood what you were asking...
atul is nearly right. You got to remove the unused items from
LinkedList after calling "print(left,..") and "print(right, ..)",
which might contain more than one item.
Since I'm not a Java guy, I just wrote some snippet using F# to
illustrate the id
@Mihir : actually you are using linked listso you are keep on adding
the nodes but not removing it..hence...you are getting wrong output..
i guess this should be done to fix the code.
public static void paths(Node node, LinkedList list) {
if(node == null) return;
list.add(node.data)
I only intend to print the root to leaf paths. The correct output should be:
721
725
It works fine when I use array instead of LinkedList.

In the statement,
i=i++ + f(i),
i++ is evaluated first. At this point i=0. The i passed to the function f()
has the value 1.
1 is printed in the function. 0 is returned. now the expression
i= i++ + f(i)
becomes
i=0+0
thus the value of i is changed to 0.
