Nucleotide Count
Given a DNA string, compute how many times each nucleotide occurs in the string.
DNA is represented by an alphabet of the following symbols: 'A', 'C', 'G', and 'T'.
Each symbol represents a nucleotide, which is a fancy name for the particular molecules that happen to make up a large part of DNA.
Shortest intro to biochemistry EVAR:
- twigs are to birds nests as
- nucleotides are to DNA and RNA as
- amino acids are to proteins as
- sugar is to starch as
- oh crap lipids
I'm not going to talk about lipids because they're crazy complex.
So back to nucleotides.
DNA contains four types of them: adenine (A), cytosine (C), guanine
(G), and thymine (T).
RNA contains a slightly different set of nucleotides, but we don't care about that for now.
To run the tests simply run the command go test in the exercise directory.
If the test suite contains benchmarks, you can run these with the -bench
flag:
go test -bench .
For more detailed info about the Go track see the help page.
