DNA Encoding
10 Points
bit-arrays
Instructions
In your DNA research lab, you have been working through various ways to compress your research data to save storage space. One teammate suggests converting the DNA data to a binary representation:
| Nucleic Acid | Code |
|---|---|
| Adenine | 00 |
| Cytosine | 01 |
| Guanine | 10 |
| Thymine | 11 |
You ponder this, as it will potentially reduce the required data storage costs, but at the expense of human readability. You decide to write a module to encode and decode your data to benchmark your savings.
1. Encode nucleic acid to binary value
Implement encode_nucleotide to accept a nucleotide and return the int value of the encoded code.
encode_nucleotide(Cytosine)
// -> 1
// (which is equal to 0b01)2. Decode the binary value to the nucleic acid
Implement decode_nucleotide to accept the integer value of the encoded code and return the nucleotide.
decode_nucleotide(0b01)
// -> Ok(Cytosine)3. Encode a DNA list
Implement encode to accept a list of nucleotides and return a bit array of the encoded data.
encode([Adenine, Cytosine, Guanine, Thymine])
// -> <<27>>4. Decode a DNA bit array
Implement decode to accept a bit array representing nucleic acid and return the decoded data as a list of nucleotides.
decode(<<27>>)
// -> Ok([Adenine, Cytosine, Guanine, Thymine])DNA Encoding
