Let's use the letter B for "hundred", the letter S for "ten", and "12...n" for the one digit n (<10), and change the format to output any positive integer with no more than 3 digits . For example 234 should be output as BBSSS1234 because it has 2 "hundreds", 3 "tens", and a 4 for the ones.

Input format: Each test input contains 1 test case, giving a positive integer n (<1000).

Output format: The output of each test case occupies one line, and outputs n in the specified format.

Input sample 1:

234

Sample output 1:

BBSSS1234

Input sample 2:

23

Sample output 2:

SS123
