Array Range

Background

Dawei is teaching the basics of arrays. To help students better understand array properties, he posed a simple problem, asking everyone to calculate the difference between the maximum and minimum values in an array.

Problem Description

Given an array length 1 or more of ints, return the difference between the largest and smallest values in the array. Note: the built-in Math.min(v1, v2) and Math.max(v1, v2) methods return the smaller or larger of two values.

Input Format

Input is given from standard input in the following format.

A single line containing multiple integers, representing the elements of the array. Elements are separated by spaces.

Output Format

Output is printed to standard output in the following format.

A single integer, representing the difference between the maximum and minimum values in the array.

Sample

10 3 5 6

7

7 2 10 9

8

2 10 7 2

8

Sample Explanation

For the first sample, the array is $[10, 3, 5, 6]$. The maximum value is $10$, and the minimum value is $3$. Their difference is $10 - 3 = 7$.

Constraints

Time limit: $1$ second, Memory limit: $1024$ KiB for each test case.
