Convert a Peptide into a Peptide Vector solved by 200

Given an amino acid string Peptide = a₁ . . . a_n of length n, we will represent its prefix masses using a binary peptide vector Peptide' with mass(Peptide) coordinates. This vector contains a 1 at each of the n prefix coordinates

and it contains a 0 in each of the remaining noise coordinates. The toy peptide XZZXX, whose prefix masses are 4, 9, 14, 18, and 22, corresponds to the peptide vector (0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,1,0,0,0,1) of length 22.

Converting Peptide into Peptide Vector Problem

Convert a peptide into a binary peptide vector.

Given: A peptide P.

Return: The peptide vector of P.

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.
