Question

I’m trying to write a function that when given 2 arguments, the 2 leftmost columns, produces the third column as a result:

0 0 0
1 0 3
2 0 2
3 0 1

0 1 1
1 1 0
2 1 3
3 1 2

0 2 2
1 2 1
2 2 0
3 2 3

0 3 3
1 3 2
2 3 1
3 3 0

I know there will be a modulus involved but I can’t quite figure it out.

I’m trying to figure out if 4 people are sitting at a table, given the person and target, from the person’s perspective which seat is the target sitting in?

Thanks

Answer 1

If a and b are the positions of the two persons, their “distance” is:

(4+b-a) % 4

This also shows that the forth block in your example is wrong.
