12th c++ problem

Posted: 02 Sep 2010 08:39 PM PDT

Little Boy Banku is mad at his teacher, who ate all the sweets in the flat and even went to the neighbours to eat their sweets too. Now Banku's parents brought home a chocolate bar, and, sure enough, School teacher is here already and wants to eat it. However, this time Banku has firmly decided that not a single piece of chocolate will go to this glutton. Banku wants to use his teacher's addiction to the games of chance and suggests playing the following game. A chocolate bar can be considered as a rectangle of square units arranged in m rows and n columns and separated by lines . Two players take alternate turns. At his turn, a player must take one piece of chocolate and split it into two along one of the lines. If a player can't make a legal move (which happens when all pieces of chocolate consist of a single unit square), he loses, and the winner takes all the chocolate. But the teacher is smart enough! He immediately understood who should make the first turn in order for teacher to win, assuming that players take optimal turns. Can you guess that?
Input

First line of input contains number of test cases. The second line of the input contains space-separated integers m and n (1 <= m, n <= 50).
Output

For each test case If teacher should start the game in order to win, output "[:=[first]" otherwise, output "[second]=:]".
Example

Input:
3
2 4
1 3
2 9


Output:
[:=[first]
[second]=:]
[:=[first]

Difficulty in implementing video conferencing on Internet

Posted: 02 Sep 2010 12:56 PM PDT

I am B.E (C.S.E) Final year student, developing a project on E-Learning.
I have designed some modules like mail,e-library etc.
I was doing video conferencing in LAN.
I have little bit idea of implementing video conferencing on LAN by using Java Media Framework through RTP protocol,
but my teacher suggested me to do that on Internet i.e a student from any location should be able to do video conferencing with the teacher at server.
I don't have any idea how to provide video conferencing on Internet.:confused:
Please give me some idea about the same.

What steps I should follow?

What will be the H/W & S/W requirements for the project?

P.S:- My teacher clearly said that she cannot guide me in this project....:(

Brief explanation of Quick Sort algorithm

Posted: 02 Sep 2010 09:32 AM PDT

On request of one user from ce,i am going to explain one of the most commonly used sorting algorithm ie quick sort

It is based on Divide and conquer approach.

It is one of the common practical example of recursion

There are generally 3 steps in this

1:-Divide a problem a multiple sub problems
2:-Solve them individually.
3:-Merge those sub problems to find solution of main problem

Algorithm

1. Choose any key element in an array which is know a pivot.
2. Reorder the array such that that all elements which are less than the pivot come before the pivot and so that all elements greater than the pivot come after it. After the partitioning, the pivot is in its final position.
3. Recursively reorder two sub-lists: the sub-list of lesser elements and the sub-list of greater elements.


Below is the program written in c++ ,it can help you for better understanding

//Program for Quicksort
#include<iostream.h>
#include<conio.h>
int partition(int a[],int,int);
void quick(int a[],int,int);
void main()
{
int *a,n,i;
cout<<"Enter size of array"<<endl;
cin>>n;
a=new int[n];
cout<<"Please enter elements for array"<<endl;
for(i=0;i<n;i++)
{
cin>>a[i];
}
quick(a,0,n-1);
cout<<"Elments are"<<endl;
for(i=0;i<n;i++)
{
cout<<a[i]<<endl;
}
getch();
}
void quick(int a[],int start,int finish)
{
if(start<finish)
{
int q=partition(a,start,finish);
quick(a,start,q-1);
quick(a,q+1,finish);
}
}
int partition(int a[],int start,int finish)
{
int x=a[finish],temp,temp1,j;
int i=start-1;
for(j=start;j<=finish-1;j++)
{
if(a[j]<=x)
{
i=i+1;
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
temp1=a[i+1];
a[i+1]=a[j];
a[j]=temp1;
return (i+1);
}
