For this assignment, implement a high score system using a SortedListHasA to sort scores from highest to lowest. Seed the high score list with a few dummy scores, ala vintage arcade games, (e. g. 555,444,333,222,111). Your program should print out a list of scores Ask the user for a new score, insert the new score in the correct position, print out the new score list let the user keep entering scores and displaying the sorted list until the user quits. (the user indicates a quit state by entering a sentinel - a negative value for a high score).
