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

> !cc
cc ddd.c
> a.out
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

Good job Farce!!!

Did you find it challenging?

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.

I found the sequence easily. just testing is taking time. i lost touch with programming

, gotta practice more.

i'm coding in c++ only anyways.

nandini, don't stop with this please

sure!!
would love to know what your logic is. We can definitely learn out of this. Well you finish with the coding first. I did it in Java.

I'll surely post problem that tests our analytical thinking and expects the same from you guys as well.

Doing was writing a poem earlier.

Punch Farce · 08-06-09, 01:02 AM

take a string = "abcdefgh";

reverse this without using any temp variables ;-)

08-06-09, 01:07 AM

give me 30 -60 mins

just to be sure...

don't we have to use any kind of temp variable?

Just post the output of the run, not the source code till
everone has a chance to attempt it.

thanks

actually I am not sure, I remember this being asked in an interview
(with Cisco I think) and I did it at that time.

Let's start trying with NO temp variables and then if that is
impossible then we can use one.

as usual post the results first and then the code after everyone completes.

nandini · 08-06-09, 01:21 AM

Did you do it in c/c++, using pointers?
A simple yes/no will do? lol

Luke Skywalker · 08-06-09, 01:26 AM

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

I was spoon fed this problem.

no,

actually let me amend my condition, I think you can use variables
for loops etc. like for (i = ..., max) etc.
Just not a temp variable to store letters from that string.

Luke Skywalker · 08-06-09, 01:32 AM

But can't recall the answer.

trying with unicode give 45 min more.

Punch Farce · 08-06-09, 01:35 AM

I am really really impressed with myself ;-)

I rememebered 3 lines of code I did in an interview 10 years back!

before = abcdefgh
after = hgfedcba

Nandini, if it means anything I think you are very much like me
technically and attitude-wise. Trust me, you are going to remember
this challenge 10 years from now ;-)

Alrighto!!!

I'll give it a try tomorrow. I am so tired that I can't concentrate.
