Challenge :- Write a program to input odd no.(n) of no.s i.e , n is odd and print it in to & fro form

Question

You 1st need to sort the elements and then it in to & fro form, like pendulum moves.
Eg:
Enter the no. of elements you want to enter - 7
Input - 65,76,14,54,89,91,27

Output:-
Sorted order - 14,27,54,65,76,89,91

To & fro form - 14 54 76 91 89 65 27

Here the elements are printed at the point where the bob of pendulum is momentarily at rest.

If the no. of inputs are even ,"print invalid input".
