Answer 1

import java.util.Arrays;
  
public class MyClass {
    public static void make_unique(int []arr) {
        int previous = arr[0];
 
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] <= previous){
                arr[i] = previous;
                arr[i]++;
            }
            previous = arr[i];
        }
    }
    public static void main(String args[]) {
        int arr[] = { 1, 1, 2, 2, 3, 3, 7, 8, 8, 8, 12, 15, 33, 33, 33 };
          
        make_unique(arr);
          
        System.out.println(Arrays.toString(arr));
    }
}
