Algorithm

  1. Create an empty list called unique_list to store unique elements.
  2. Iterate through each element, element, in the input list.
    • Check if the element is not already in unique_list.
      • If true, add the element to unique_list.
  3. After iterating through all elements in the input list, return the unique_list.
  4. The returned unique_list contains only the unique elements from the input list.
