I haven't studied Linear Algebra yet, but I did like how elegant your solution was. Nice job!
Yeah, I think the other solutions are different forms of this one. It'd be harder to figure out if you haven't studied linear algebra yet.
Is this a common method of solving this type of problem?
In Python I get the error.
261998765738225392543588155392 should equal 261998765738225395043321056933
So for small numbers is works pretty good. How can I handle bit int in python?
More of a challenge in Mathmatics than Programming.
why use bigint? i'm just know why?
Why are the arguments signed and the result unsigned?..
Yes, see the issue below.
Does C++ has overflow issue?
When I hit run, only 2 random cases are tested?
