I am guessing that the transformation should have been
1 E
1 E
1 E
2 C
2 D
3 B
3 E
3 D
4 C
4 E
4 D
5 D
5 E

I'm not that great at scripting which somebody else will no doubt
suggest, so personally I'd write a little C/C++ application to do it.
I've got a string parsing function that I wrote to split a string
into white space delimited fields and return a count of the number of
fields, which would be a good starting point for this.
