Answer to Question #14898 in Java | JSP | JSF for Kaze

Question #14898
Write the body of method getRange:

public static int getRange(int[] a){

which takes an array of integers as parameter and counts the range from the array. For example, if the parameter array holds values {2,5,-4,8,3}, the getRange method returns 12.
Expert's answer
public static int getRange(int[] a) {
int min = a[0];
int max = a[0];

for (int i = 0; i < a.length; i++) {
if (min > a[i]) {
min = a[i];
} else {
if (max < a[i]) {
max = a[i];
}
}
}
if (max < 0 && min < 0) {
return min * -1;
}
if (min < 0) {
min *= -1;
return!min!+!max;
}
return max - min + 1;
}

int[] a = {-8, -3, -2, -1};
