import java.util.*; public class ArraySubtract { // Given an array with numbers 1-5, how would you subtract one number from every // EVEN number in each index public static void main(String[] args) { int arr[] = { 2, 4, 5, 7, 10 }; List output = new ArrayList(); for (int i = 0; i < arr.length; i++) { if (arr[i] % 2 == 0) { output.add(arr[i] - 1); } else { output.add(arr[i]); } } System.out.println("Output Array : " + output.toString()); } } OUTPUT: Output Array : [1, 3, 5, 7, 9]

Question is simple - Make ODD NUMBERS ARRAY. So for that subtract "1" from all even numbers. on
