1. Do not check special characters such as '.' ','... only check characters 'a' - 'z' or 'A' - 'Z'
for example:
b
#
a. cd. .
output:
b. cd. .

2. Do not check equal strings
for example:
world
#
world world world

output:
world world world
0

3. Do not check strings having different length

>>3. Do not check strings having different length
I always had WA 2! WTF I thought... but when I did as you said - I got AC.
Authors should fix this problem...

'Your teacher must have forgotten that her pupils sometimes forget to write letters and even sometimes they write extra letters - excellent!'

So its wrong I think...
input:
hello
#
hekllo my dear andrew!

output should be:
hello my dear andrew!
1

but instead we have:
hekllo my dear andrew!
0

Am I wrong?

I support Andrew Shmig. This ambiguity in problem statement should be fixed.
Really, since pupils can add extra-letters, word "probleme" with extra "e" in it's end is written with 1 mistake.

problem is correct, when it is talking about extra-chars-mistakes - it is about not to check it, because teacher forgot this! so your program shouldn't do that, teacher do not want this functionality )
