Question
Write a method called range that returns the range of values in an array of integers. The range is defined as 1 more than the difference between the maximum and minimum values in the array. For example, if an array called list
contains the values {36, 12, 25, 19, 46, 31, 22}, the call of range(list) should return 35 (46 - 12 + 1). You may assume that the array has at least one element.
Answer
Implementation of range method:
public static int range(int[] list)
{
int maximum = list[0];
int minimum = list[0];
for(int i = 1; i < list.length; i++)
{
if(list[i] > maximum)
maximum = list[i];
if(list[i] < minimum)
minimum = list[i];
}
return (maximum - minimum + 1);
}
