I have WA on test #7. I read about thing that blogger is not friend of himself. My program gives correct answer in this case.

There is a phrase in the statement, that we need to sort list alphabetically. So i have a question. if the list has three items "A" "a" and "_" which order we need to output?

Could somebody help me?

Thanks beforehand.

Input:
3
a
<blog>
<friend>c</friend>
</blog>
b
<blog>
<friend>b</friend>
</blog>
c
<blog></blog>

Output:
a
1: c
2:
3:

b
1:
2:
3:

c
1:
2: a
3:

My program passes this test, so I think bug is somewhere else. But in any case, thanks.
