## Task 4 - 100734

According to the legend, the Bohemian Queen Libussa made the granting of her hand dependent on the solution of a riddle that she gave to her three suitors:

"If I give the first suitor half of the contents of this basket of plums and one more plum, the second suitor half of the remaining contents and one more plum, and the third suitor half of the now remaining contents and three more plums, the basket would be emptied. Name the number of plums that the basket contains!"
