PROGRAMMING:Strive for the top three
Because the top three students have awards, so we all want to get the top three. Input several student grades (no more than 100) from the keyboard and output the top 3 grades of each group.
###Input format:
A line, enter several student grades (integer, range 0 ~ 100), separated by spaces, ending with a negative number (Note: the negative number at the end is not the student grade).
###Output format:
One line, output the top three with the highest score, separated by spaces, no spaces at the end, if less than three people, use the character #.
###Input example:
```in
99 45 78 67 72 88 -1
```
###Output example:
```out
99 88 78
```
