Harmonious Array Checker

A harmonious array is defined as an array where the difference between its maximum and minimum elements is exactly \(1\), i.e. \(max - min = 1\). Given an array of integers, your task is to determine if the array is harmonious.

If the array is harmonious, print True. Otherwise, print False.

The program should read from standard input (stdin) and output the result to standard output (stdout).

inputFormat

The first line of input contains a single integer \(n\) denoting the number of elements in the array. The second line contains \(n\) space-separated integers representing the elements of the array.

outputFormat

Output a single line containing either True or False depending on whether the array is harmonious.
