Thread: programming challenge...

Here is something which will surely test your programming skills.

You have one character array:-
char[] charArray={'a','b','c','d','e','f','g','h','i','j' ,'k','l','m','n','o','p'};

and an emtpy 2 dimensional char array:-
char[][] char2DArray=new char[4][4];

Now the challenge is that you've to arrange char2DArray like this:

a c f j
b e i m
d h l o
g k n p


anybody up for game?

I am in for it but have time only at week end

Simple use unicode of letter.

sure!!!

I had got that problem yesterday. I got some leisure time today and managed to code for it successfully (don't know whether it's efficient ).

Solve it whenever you get time.

sure, thanks for the time

i guess there is a matrix solution for this

Look buddy I've not asked for any help, so no need to give any tips. We all know you're a genius. So can you please restrain yourself from enlightening us, atleast in this thread?

I'll try it too. should be able to remember how I did it 10 or 20 years back ;-)

I am not a genius.
I just gave a tip.
I think this thread is great & we can post new challenges.
@Farce I did this 3 years ago.

you don't need to be good in mathematics in order to solve it.
It'll be good for you NPU.

No.

No. You are master of all trades & jack of none.

Here's a sort of 'cheating' solution, but very efficient ;-)

:lol:

voldemort had 7-8 copies of himself, no one knows how many farce has :-P

He had 7 as seven is magical number. So had Farce.
Now avoid off topic & post answer only.

OK, I have done a quick and dirty solution. I won't post the source code
till others have finished.

source = 0, row = 0, col = 0, nr = 0, nc = 0
source = 1, row = 1, col = 0, nr = 1, nc = 0
source = 2, row = 0, col = 1, nr = 1, nc = 0
source = 3, row = 2, col = 0, nr = 2, nc = 0
source = 4, row = 1, col = 1, nr = 2, nc = 0
source = 5, row = 0, col = 2, nr = 2, nc = 0
source = 6, row = 3, col = 0, nr = 3, nc = 0
source = 7, row = 2, col = 1, nr = 3, nc = 0
source = 8, row = 1, col = 2, nr = 3, nc = 0
source = 9, row = 0, col = 3, nr = 3, nc = 0
source = 10, row = 3, col = 1, nr = 3, nc = 1
source = 11, row = 2, col = 2, nr = 3, nc = 1
source = 12, row = 1, col = 3, nr = 3, nc = 1
source = 13, row = 3, col = 2, nr = 3, nc = 2
source = 14, row = 2, col = 3, nr = 3, nc = 2
source = 15, row = 3, col = 3, nr = 3, nc = 3

Yes, it was challenging, since it took me a few iterations to
get the logic right, and still I think I should improve the code
and make it more elegant ;-) next version coming up soon.

I didn't post the source code, so you have no idea how I did it ;-)
I could have hardcoded the entire thing ;-)
sorry, please continue with your coding, don't stop.

This problem was asked in the interview which I missed last week.
