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.

take a string = "abcdefgh";

reverse this without using any temp variables ;-)

-F

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.

-F

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

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.

-F

But can't recall the answer.

trying with unicode give 45 min more.

I am really really impressed with myself ;-)

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

> !cc
cc rrr.c
> a.out
before = abcdefgh
after = hgfedcba

Don't give us complexion, Farce.

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.

I think I need to sleep.
My program had change & giving me this:
p p p p
p p p p
p p p p
p p p p

you have P'd a lot ;-)

i = -1;
n = 0;
j = 0;
k = 0;
l = 0;
while (n <17)
{
if (i < 3)
{
i++;
k = 0;
}
else
{
l++;
k = l;
}
for (j = 0; j<= i-l; j++)
{
char2DArray[i-j][k]=charArray[n];
n++;
k++;
}
}

more complexion coming up.
version 2.0 with more features and flexibility ;-)

does this work? plese post output. (please don't post source until later)

thanks

are you guys discussing a different program, i jus got the answer for the first one ...

should i post it now ??

it is difficult to tell from pri's code ;-) but it is the first one.

yes please, just the results, let's give Luke some time till we
post the code.

yes it worked on dry run

i = -1;
n = 0;
j = 0;
k = 0;
l = 0;

while (n <17)
{
if (i < 3)
i++;
else
l++;

k = 0;
for (j = 0; j<= i-l; j++)
{
char2DArray[i-j][k]=charArray[n];
n++;
k++;
}
}

Try this farce ;-)

class Math
{
public static void main(String[] args)
{

char[] charArray={'a','b','c','d','e','f','g','h','i','j' ,'k','l','m','n','o','p'};
char[][] char2DArray=new char[4][4];
char[][] a=new char[4][4];


for(int x=0; x<charArray.length; x++){
for(int d=0; d<char2DArray.length; d++){
for(int b=0; b<char2DArray[d].length; b++){


char2DArray[b][d] = (char)charArray[x];


}}}
for(int i = 0; i <= 3; i++) {
System.out.print("");
for(int j = 0; j <= 3; j++) {
System.out.print(" " + char2DArray[i][j]);
}
System.out.println("");
}
System.out.println();
}
}

What the hell had happened that this is not copying?
@Farce can I pm you my poetry again?
