Ruby で書いた。出力は、
[["1"], ["2"], [nil, "1"], [nil, "2"], [nil, "3"], [nil, nil, "3"]]
[["2"], ["3"], [nil, "2"], [nil, "2"], [nil, "3"], [nil, nil, "4"]]
[["3"], ["4"], [nil, "3"], [nil, "2"], [nil, "3"], [nil, nil, "5"]]
[["4"], ["5"], [nil, "4"], [nil, "2"], [nil, "3"], [nil, nil, "6"]]
[["5"], ["6"], [nil, "5"], [nil, "2"], [nil, "3"], [nil, nil, "7"]]
