Subdividing a column

[mesh01]

Hi,

I have an "input.txt" file which contains this column of numbers:

5 
77 
1
-4
9
17
13
2
1
5
63
8

I would like that column to be divided into columns side by side, whose the number of elements is established by this vector:

(4,2,5,1)

Output should look like this:

Output:
 5     9    13    8
 77   17     2
 1           1        
 -4          5   
            63

The output should be saved in an "output.txt" file.

Any tips?

Thank you,

m.
