Question

(b) public static int sqrtDiff(int array[]) - this method should return the square root of the difference between the largest number in array and the smallest number in array. For example, if array = {45,13,51,84,157,67,45,93,22}; max=157, min=13, square root of the difference: √157 − 13 = √144 = 12

LANGUAGE IS JAVA

Answer 1

public static int sqrtDiff(int array[]){
    if(array.length>0) {
        int max = array[0], min = array[0];
        for (int i = 0; i < array.length; i++) {
            if (max < array[i]) {
                max = array[i];
            }
            if(min > array[i]){
                min = array[i];
            }
        }
        return (int) Math.sqrt(max-min);
    }
    return -1;
