the result is:
1 1 2
1 1 2
2 1
3 1
each row has different number of columns. What is 3:2 mean?

first line: 1 is [1], 1:1 is [1], 2:2 is [2], 3:2 on to 16:3 are all [] (empty), so the first line is [1 1 2]
third line: 2 is [2], 1:1 is [1], 2:1 is empty, 3:1 through 16:3 are all [], so the third line is [2 1]. That is a different length than the first line.
