Question

assume that input is an int array. the array is already declared and initialized wnd every element is assigned to an integer number. in addition assume that the array contains at least 1 element. write a code that contains one while loop abd no other loops to find both maximum and minimum numbers from input. then outout the maximum minus the minumum to the console window. (using java eclipse coding)

Answer 1

Thanks for the question, here is the code, where i have used only 1 while loop to iterate all the numbers in the array and find out the min and max number in the array. Once done, at the end have output the maximum and minimum numbers to the console window.

public class MaxMin {

    public static void main(String[] args) {

        int array[] = {1, 2, 3, 4, 5, 6, 7, -352, 9, 26, 6, 6, -35, 7, 8, 535};

        int min = array[0];
        int max = array[0];
        int index = 0;
        while (index < array.length) {
            if (array[index] < min) min = array[index];
            if (array[index] > max) max = array[index];
            index+=1;
        }

        System.out.println("min = " + min);
        System.out.println("max = " + max);

    }
}
