code guessing, round #3 (completed)

started at ; stage 2 at ; ended at

specification

hello
The challenge for round 3 of the code guessing competition is to multiply two square matrices.
In python: your function will be passed two arguments, m1 and m2. each of these arguments is a list of rows, each of which is a list of values. that is, m[a][b] is the number at row a, column b in the matrix m. you must return a list of lists in the same format that is the result of the multiplication m1*m2. you can assume that both matrices are square and that both are the same size.
in c: your function has the prototype int* entry(int* m1, int* m2, int n). each matrix argument is arranged by rows first, so m[(a*n)+b] is the value in the matrix m at row a and column b. n is the size of the matrices. you must return an array of ints in the same format as the input that is the result of the multiplication m1 * m2.

There is a test suite. You cannot have it. Muahahahaha. -gollark
submissions can be in c or python

'''This script provides a function `entry` that multiplies two square matrices together.                
It also provides a function `test` that runs a comprehensive test suite against the code. By default, this is run every time the script executes.                
           
It uses typing features from python 3.10.  
            
In 3.10+, `typing_extensions.Unpack[Ts]` must be replaced with `*Ts`,  
`typing_extensions.TypeVarTuple` must be replaced with `typing.TypeVarTuple`,   
and `typing.Union[A, B]` must be replaced with `A | B`.
