you hard coded the numbers friend , its supposed to read from the user input

 

[MihiCherub]

Yes it is. That's how it demonstrates the user inputs. You don't have to use the Scanner class. All you have to do is grab the data and do the math. As long as you able to get the output exactly similar to the question you're done.

Here is a simple challenge

Make a 1000 Line of 'A' without using for,while,do..while..goto..
or the new line character(\n) and with the least amount of codes.

USE ONLY JAVA
example out put..

A

I am little bit busy machan. What you're asking is bubble sort method. I don't have hands on experience with this so i don't like to be the wise guy by copy pasting a code from internet.

Great work by posting this thread machan. This will help lots of people to face better in their technical interviews. Specially Virtusa, WSO2.

Competitors, please try to avoid JDK or Language facilities to solve problems. Like arrays.sort(); Big companies expect you to learn those functions but they need to know that you know the theory behind it.

It's the logic that matters.

 

[Tulip_Doll]

This isn't really good in performance machan. For 100 element array, you need 10000 iterations total.

this was only for what he asked , you can always get it from a file

here is my challenge.
(I work for a company as a security audit, and this is a cryptography 101 algorithm. There are no "perfect" algorithms and such algorithms are not practical for today. But if you can write a good one, you are many steps ahead in your programming career! At least give it a try.


You need to write an algorithm that accepts a 32 bit integer. Then, it has to provide two integers back, that when multiplied, produces the given number. Now the challenge is that BOTH of these returns values should be Prime numbers. If it can't find a prime number factorization, it should return 0.

Example: input = 35; output should be "7 * 35".
Input = 143; output should be 11*13 because 11*13 = 143.

You can find examples off the internet. But try to write one first.

Winner is chosen after a reasonable number of submissions. Fastest code wins.
At the time of evaluation, a sample input will be given, and the snippet that takes the smallest amount of time yet provides the correct answer wins.
