Considering a 3x3 matrix A, sort the prime numbers of each row in ascending order. For exemple:
input A=[5 8 2 4;
1 11 1 5]
output B=[2 8 5 4;
1 5 1 11]
You don't have to sort the other numbers, just the prime numbers.
Not sure why the problem title says "3x3 matrix", then uses non-3x3 matrices in the example and test suite. Considering rewording for clarity.
Works only because of limited test suite.
