int[] array_nums = {77, 77, 65, 65, 65, 77};
System.out.println("Original Array: "+Arrays.toString(array_nums));
int num1 = 77;
int num2 = 65;
System.out.println("Result: "+result(array_nums, num1, num2));
}
public static boolean result(int[] array_nums, int num1, int num2) {
for (int number : array_nums) {
boolean r = number != num1 && number != num2;
if (r) {
return false;
