Greedy array permutation problem

Правка en1, от aakarshmadhavan, 2018-07-16 10:03:58

This is supposed to be a greedy problem solved using stack.

Can someone give some ideas on how to proceed with it? I can't think of a proper solution or how to solve this through overall. Any help is appreciated!
