Re: 1229 - Sub-dictionary (Why WA)

There is one space character(' ') at the last of each input line in the sample input.
Should we consider this for every input?

Can anyone clarify this issue?

Re: 526 String Editing

In the output specification it is said that
Actually many command lists can satisfy the request, but only one of them is required.

is this output valid for input-2:

Code: Select all

4
1 Insert 3,b
2 Insert 5,a
3 Insert 6,a
4 Insert 7,a
