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

Question

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.

Answer 1

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;
     }

Examples

1)
 input
         int[] a = {-8, -3, -2, -1};
         int range = getRange(a);
output
         range is: 8
2)
   input
      int[] a = {2, 5, -4, 8, 3};
      int range = getRange(a);
   output
range is: 12
3)
   input
      int[] a = {1, 2, 11, 4}};
      int range = getRange(a);
   output
      range is: 11
