Is there a difference between “throw” and “throw ex”?

How to find all combinations of coins when given some dollar value
...
It stems from the number of polynomial solutions n1 * coins(0) + n2 * coins(1) + ... + nN * coins(N-1) = money. So for money=0 and coins=List(1,2,5,10) the count for combinations (n1, n2, n3, n4) is 1 and the solution is (0, 0, 0, 0)....
