The problem description says the output array elements can be in any order but the test cases seem to prefer some unknown order. Solution 682952 produces an array with same elements as the actual solution but the tests fail. Need a better description of the output desired or a more robust test suite.
Solution 682952 produces correct array, but doesn't pass it to the output.
Good Problem :)
This (and others, including Solution 1444556) only pass because of a mismatch between the Test Suite and the Problem Statement.
Sorry, I don't normally do this, but my curiosity about the whole regexp() thing finally got the better of me...
yes, but you are blocking others from learning the optimal solution. lame
