Nucleotide Count in Perl 6
Given a DNA string, compute how many times each nucleotide occurs in the string.

Given a single stranded DNA string, compute how many times each nucleotide occurs in the string.
The genetic language of every living thing on the planet is DNA. DNA is a large molecule that is built from an extremely long sequence of individual elements called nucleotides. 4 types exist in DNA and these differ only slightly and can be represented as the following symbols: 'A' for adenine, 'C' for cytosine, 'G' for guanine, and 'T' thymine.
Here is an analogy:
- twigs are to birds nests as
- nucleotides are to DNA as
- legos are to lego houses as
- words are to sentences as...
Running the tests
There is a test suite and module included with the exercise.
The test suite (a file with the extension
.t) will attempt to run routines
from the module (a file with the extension
Add/modify routines in the module so that the tests will pass! You can view the
test data by executing the command
perl6 --doc *.t (* being the name of the
test suite), and run the test suite for the exercise by executing the command
prove . --exec=perl6 in the exercise directory.
You can also add the
-v flag e.g.
prove . --exec=perl6 -v to display all
tests, including any optional tests marked as 'TODO'.
