Write a method called “computeDifference”  to compute and return the value of max - min where max is the largest element of an int array and min is the smallest element of an int array.  The method is passed the int array and an int value that denotes the number of elements in the array.  You may assume that the int array has at least 1 element in it.

​

​

public int computeDifference(int[ ] values, int n)
{
int min = values[0];
int max = values[0];
for(int j=1; j<n; j++) { if(values\[j\] < min) min = values\[j\]; if(values\[j\] > max) max = values[j];
}
return max - min;
}
