c++ - Efficiently storing DNA base-pair data in RAM? -


very related question: most efficient way store big dna sequence? , one: declaring new data type dna

i'd find way efficiently store long sets of characters actg without wasting entire byte each value, when should require 2 bits. however, don't see descriptions in responses regarding how go storing 2-bit data in c++, or java or language matter, although figure c++ should ideal language it.

so question this, syntax create conveniently usable 2-bit data type? assume sort of structure going need made fill byte-sized(lol) chunks of data, i'm not certain.

i'd interested in knowing if such thing possible in other languages well, such javascript or perl, how go in c++.

example code appreciated, thank you.

i suggest encode data in std::bitset , store bitsets in std::vector. can code dna pair in bitset , waste 4 bits per element in vector or code 2 dna pairs in each bitset , have perfect storage.
