Determine all integers n \geqslant 2 such that there exists a permutation x_0, x_1, \ldots, x_{n - 1} of the numbers 0, 1, \ldots, n - 1 with the property that the n numbers x_0, \hspace{0.3cm} x_0 + x_1, \hspace{0.3cm} \ldots, \hspace{0.3cm} x_0 + x_1 + \ldots  + x_{n - 1}are pairwise distinct modulo n.
