Write a method called smallestLargest that accepts a Scanner for the console as a parameter and asks the user to enter numbers, then prints the smallest and largest of all the numbers supplied by the user. You may assume that the user enters a valid number greater than 0 for the number of numbers to read. Here is a sample execution:

How many numbers do you want to enter? 4

Number 1: 5

Number 2: 11

Number 3: -2

Number 4: 3

Smallest = -2

Largest = 11
