We can also invert the conversion of a peptide into a peptide vector, so that the terms "peptide" and "peptide vector" can be used interchangeably.

## Converting Peptide Vector into Peptide Problem

Convert a binary vector into a peptide.

Given: A space-delimited binary vector P.

Return: A peptide whose binary peptide vector matches P. For masses with more than one amino acid, any choice may be used.

Note: In this chapter, all dataset problems implicitly use the standard integer-valued mass table for the regular twenty amino acids. Examples sometimes use imaginary amino acids X and Z having respective integer masses 4 and 5.
