Click the OK button or press the Enter key each time you enter a file number in the text box below. If you accidentally enter the error, press the Delete button to delete the selected record. If you enter the same as the previous part of the previous number, you only need to enter a different number after the number. After entering all the numbers in the out-of-order order, click the “Start Sort” button, and then place each file in the corresponding position in the corresponding heap according to the instructions in the list, and finally put the files of each heap. According to the serial number of the heap, they are merged from small to large, which is exactly the order.
