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.




Public Sub Main()
Dim sList As String = File.Load("../FASTA")
Dim sTemp, sOutput As String
 
For Each sTemp In Split(sList, gb.NewLine)
  If sTemp Begins ">" Then
    If sOutput Then Print sOutput
    sOutput = Right(sTemp, -1) & ": "
  Else
    sOutput &= sTemp
  Endif
Next
 
Print sOutput
 
End
