I am watching a lecture on threading and they use the term m-ary vector as follows:
"Let [X] represent an m-ary vector of non-negative integers"
What is this? Is the arity the length? I presume a vector is merely a sequential data structure like an array? Why would the letter m be used – I have only ever seen n-ary previously.
Yes.
Yes.
There are twenty-six latin letters that could be used. If — later — they are going to talk about two different length vectors, they’re going to need to different letters.
