Can you fill a 4x4 square so each row and each column forms a prime number? And a 5x5 square?
Note: in both cases, there should be no duplicate rows or duplicate columns. Also, numbers cannot start with a 0. Finally, all digits from 0 to 9 should be used at least once.
whoops i just realized that i miss read the problem, i had thought that
each row and column had to sum up to be a prime number, which is quite
easy.. heres what i did anyways
