*FRIDAY CHALLENGE* : write a code that gets as input a positive number N > 1 and prints a N x N CLOCKWISE-SPIRAL-SQUARE

Question

Example:

if N=3 then the Clockwise Spiral Square looks like this:
1 2 3
8 9 4
7 6 5

if N=5 then the Clockwise Spiral Square looks like this:
1 2 3 4 5
16 17 18 19 6
15 24 25 20 7
14 23 22 21 8
13 12 11 10 9
(In this example the columns don't align perfectly, but in the output of your code the columns should left-align)

-Start at top left with 1.
-numbers increase by 1 until N*N
-flow of increasing numbers spirals inward maintaining the square shape

Answer 5

@Michal, my code is higher up in this thread.

Answer 6

Ok. The response was fantastic. Here is my version.
It is definately not the best.
All recursion.

It is too difficult to pick a winner. I think everyone had fun and the warm feeling you get from accomplishing the task is enough.
Congrats to all.

Answer 11

@Krishna Excellent js implementation. There are many advantages to using a html,css,js for the solution. The allignment for one is much easier. Well done!

Answer 12

Hi Pikachu, I thought it out myself. If there is duplication, it is unintentional.

Answer 13

Hi...

I guess it's still Friday (at least here in Croatia :)).
This is my try:
https://code.sololearn.com/cDS30H352Qv8/#java

I don't really know what to think about it.
I wrote it and then glanced at some other solutions and all of them are nuclear science to me... but I hope I'm closing the gap :D

Bye & good night.

Answer 14

@Onkar. In my code and some others I tested, I got 1 as output with input 1 which is correct. Please specify how you got -1. Also note the challenge asks for N>1.
