are test #3 and #4 correct?
Sorry Rifat, I've messed up test cases. Rescored now.
Arrays are not a natural number..for the tests I mean
@Lorenzo, the input to solution function is always a single number. I've used arrayfun to make multiple tests in a single test case.
I think Test 3 and 4 are (still) faulty. The functions "any" and "all" must be swapped.
Sums with Excluded Digits
Swap the input arguments
Matrix indexing with two vectors of indices
Getting the indices from a vector
Extra safe primes
Polite numbers. Politeness.
