"than u"? Is "111" a number, or do you mean the vector [1, 1, 1]? Does it matter, that the input is [1,1; 2,2; 3,3], when the posted example of the output seems to be all combinations of the numbers [1,2] with repetitions? Where is the 3 in the output?
Please edit the question and explain exactly, which inputs should produce which outputs.
