p00136 Frequency Distribution of Height
The height of the student was measured at the medical examination. Create a program that takes height data as input, creates a frequency distribution, and outputs it. The frequency distribution is divided into 6 classes in 5 cm increments, and the number of people is indicated by * (half-width asterisk). However, if the frequency (number of people) of that class is 0, output only the class heading.



Input

The input is given in the following format:


n
h1
h2
::
hn


The number of students n (1 ≤ n ≤ 40) is given to the first line, and the real number hi (150.0 ≤ hi ≤ 190.0, up to the first decimal place) representing the height of the i-th person is given to each line after the second line. ..

Output

Display the frequency distribution in the following format.


Line 1 Heading "1:" followed by * for people less than 165.0 cm *
2nd line Heading "2:" followed by people 165.0 cm or more and less than 170.0 cm *
3rd line Heading "3:" followed by the number of people from 170.0 cm or more to less than 175.0 cm *
4th line Heading "4:" followed by the number of people from 175.0 cm to less than 180.0 cm *
Line 5 Heading "5:" followed by the number of people between 180.0 cm and 185.0 cm *
Line 6 Heading "6:" followed by * for people over 185.0 cm *
