Can Form Arithmetic Progression

Given an array of integers, determine if it can be rearranged to form an arithmetic progression. An arithmetic progression is a sequence where the difference between any two consecutive elements is constant. In mathematical terms, an arithmetic progression is defined as: (a,, a+d,, a+2d,,\dots). Note that if the array has fewer than 2 elements, the answer is considered False.

inputFormat

The first line contains an integer (n) which denotes the number of elements. The second line contains (n) space-separated integers representing the elements of the array.

outputFormat

Output a single line: either 'True' if the array can be rearranged to form an arithmetic progression, or 'False' otherwise.## sample
