with a lot of new IITs this time , u can expect all closing ranks to come down this time.

so I think u can get in IIIT hyderabad also

there was a difference of more than 10 marks when i checked the solutions from 2 different sites. so u don't have to trust the sites so much.

try to check the solutions from different sites.

i got 206 marks.

my calculated marks were 200 and 210 .

#include<iostream.h>

void main()

{

int w,x,y,z,p;

cin>>w>>x>>y>>z;

p= w+x/y-z;

cout<<p;

}

@ pramod - you've messed up again.

I don't understand how you get m=6 and n =8

Going by your calculation , we will get

a= ( 169 n - 121m) / 2

which gives a = 313 and b= -19

You got a+b= 28 because your value of (a+b) is wrong.

(a+b) = (156n -110m)/2

Consider some rational exponent.

2^2.5

This is equal to 2^5/2 = Which we know how to calculate.

Similarly, = 2^1.732... = 2 ^1732/1000 =  

This is not the exact value , but this is how it is defined

I've proved that a+b>=2 . So is'nt the job done?

u have to prove that the it is possible to achieve the value 28 for some permissible values of a and b.

Not necessary . the minimum value of a+b might be more than 28 . u may still be able to prove that a+b>=28

e.g. It can be proved that a+b >=2 ( because both a and b are positive integers.)

 Does that mean that the value 2 can be achieved?

a and b have to be positive integers. if u put m=n=1 , a and b will not be positive.

The answer given by oneyeartogo( now deleted)  is also not perfect. you have only proved that a+b>= 28. it has not been proved that the value 28 can be achieved. In olympiads , such things matter a lot .

the answer is.....   . ok do it urself

Here is an another way of hacking passwords. make an email ID with the username something like retrive_pass@yahoo.co.in . Copy the entire post given above  and replace retrive_pass_tm@yahoo.co.in with the email ID u just made. Paste it on some forums or send it as email to ur friends.

And zooooooooom!!! brainless idiots will start sending emails to that address along with their passwords.

1 pound = 0.45359237 kilograms

For any type of conversions , just type it in google search in the following format:

1 lb in kg

OR

1 INR in USD

and so on..

For C++ , read The C++ Programming language by bjarne stroustroup

For algorithms , see Introduction to algorithms ( CLRS )

kranzz, check ur nudgebook.

Sumita Arora teaches the 1994 version of turbo c++ .

a lot of changes have been introduced into c++ in the last decade.

you can't study such ancient indian texts in a subject as dynamic as computer science.

try http://www.cplusplus.com/doc/tutorial/introduction.html .

by the way , you don't have to learn C++ before you reach IIT. you 'll learn it from there just like any other subject.
