A sample Problem

Sample Problem : The Smallest Gutibaz

You have N varsity friends. Some of them are tall and some are

short in size . Among them there is one who is the smallest in size

whenever you see him in public.

From the given N heights of your friends you to find the height of

the dangerous “Choto Gutibaz”.

Input Format:

The first line contains a single integer N. The next line contains N

space-separated heights Height[i].
