Wow you so clever!!!

In the random test it expected "Expected: equal to [ [ 0, 91, 15, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 159, 108, 13 ], [ 4, 68, 93, 0 ] ]" but first vector must contain equal numbers please fix it
