## under construction ### Like LeetCode but more lightweight if you want to contribute write tests like this: ```python import unittest # def revstring(x): return x[::-1] # class TestSolution(unittest.TestCase): def test_simple(self): # !! This needs to be dynamic ; if the user enters some shit then it is supposed to work too x=""; self.assertEqual(revstring(x), x[::-1]) if __name__ == "__main__": unittest.main() ```
