  public static void main(String[] args) {
    int[] arr1 = new int[] {1,2,3,4};
    int[] arr2 = new int[] {1,3,2,4};
    
    boolean isEqule = Arrays.equals(arr1, arr2);
    System.out.println(isEqule);
    
    
    System.out.println(Arrays.toString(arr1));
    Arrays.sort(arr2);
    System.out.println(Arrays.toString(arr2));
    
    
    int[] a = new int[] {1,2,3,4,5,6,7,8,9,0};
    
    int index = Arrays.binarySearch(a, 9);
    
    System.out.println(index);
