Insert 10 integers (generated randomly between 20 and 60 , do not insert duplicates) into list 1 in the main method. 3. Insert 15 integers (generated randomly between 20 and 60 , do not insert duplicates) into list 2 in the main method. Repeat the process for list 3. 4. Write a method to print the elements of a list, 5 elements per line and apply it on list1. 5. Write a method to find and return the smallest value in a list and call it for list2. 6. Write a method to find the average of the even numbers in a list and use it for list3. 7. Given two lists as parameters, write a method to find the elements that are in the first list but not in the other list and insert them into a third list (the difference). The third list is returned by the method. Apply the method on list2 and list 3 , respectively. 8. Write a method to print a list in reverse order and apply it on list1
