2017-6: k-mers
The term k-mer typically refers to all the possible substrings of length k that are contained in a string. In computational genomics, k-mers refer to all the possible subsequences (of length k) from a read obtained through DNA Sequencing. Write a function that takes a character vector as its right argument and k (the substring length) as its left argument and returns a vector of the k-mers of the original string.
Examples:
4 (your_function) 'ATCGAAGGTCGT'
┌────┬────┬────┬────┬────┬────┬────┬────┬────┐
│ATCG│TCGA│CGAA│GAAG│AAGG│AGGT│GGTC│GTCG│TCGT│
└────┴────┴────┴────┴────┴────┴────┴────┴────┘
4 (your_function) 'AC' ⍝ k>string length? Return an empty vector
