Puppet Show

CodeChefOpen on judge ↗

$N$ children are watching a puppet show standing in a queue. Some of them are unable to enjoy the show because of a taller (strictly taller) child in front of them. Help them to reorder themselves such that everyone enjoys the show. The Show has already begun so you have to do it as quickly as possible. [Note: One swap takes one unit of time. A swap is an exchange of positions of two children.] #
