In bioinformatics, long character strings are often encoded in a format called FASTA.

A FASTA file can contain several strings, each identified by a name marked by a > (greater than) character at the beginning of the line.



Task

Write a program that reads a FASTA file such as:

>Rosetta_Example_1
THERECANBENOSPACE
>Rosetta_Example_2
THERECANBESEVERAL
LINESBUTTHEYALLMUST
BECONCATENATED


Output:
Rosetta_Example_1: THERECANBENOSPACE
Rosetta_Example_2: THERECANBESEVERALLINESBUTTHEYALLMUSTBECONCATENATED

Note that a high-quality implementation will not hold the entire file in memory at once; real FASTA files can be multiple gigabytes in size.




a$ = ">Rosetta_Example_1
THERECANBENOSPACE
>Rosetta_Example_2
THERECANBESEVERAL
LINESBUTTHEYALLMUST
BECONCATENATED"
 
i = 1
while i <= len(a$)
  if mid$(a$,i,17) = ">Rosetta_Example_" then 
    print 
    print mid$(a$,i,18);": ";
    i = i + 17
   else
    if asc(mid$(a$,i,1)) > 20 then print mid$(a$,i,1);
  end if
  i = i + 1
