I'm assuming that this code is for Vestigium. There are 2 problems I can
see so far:
1. In `main()` function, `for _ in range(1,int(input())+1)` is for each
test case, and that is good. What is not good is `for i in
range(1,order+1)`. Why are you iterating through each `order`, and creating
a matrix, calculate, and print *for each order*? You should do that once
for each test case.
2. In CreateMatrix function, `a.append(int(input()))` would throw error.
The rows are given to you as a whole as space-separated numbers and cannot
be converted to `int`. Note that when the input gives you the matrix, *each
input is one row*, so you should not iterate through each column in the row
above.
