Hi there,

I am trying to solve a problem with Mathematica. You
have numbers from 1 to n all
numbers twice , namely.

1 1 2 2 3 3 4 4 5 5   for example for n=5

I am trying to sort the numbers o that between two 'n's
there must be exactly n

For example if n=3 the solution is
2 3 1 2 1 3  .  You see there is 1 number between 1 and
1. and 2 numbers between 2
and 2, and 3 between 3's.

I know this forum is not for asking problems. But i am
learning Mathematica and
wanna see how professionals solve a real problem with

Thank you very much for giving me a chance to ask my
Best wishes to everyone.
