Getting WA! Please help.

Code: Select all

Removed After AC!

Getting WA! Please help.

From the output specification: In addition, after each output line, you must print an empty line. There are no exceptions for the last test case.

In addition, try the cases:

Input

Code: Select all

3QE
Z55

Output

Code: Select all

3QE -- is not a palindrome.

Z55 -- is not a palindrome.

[blackheartadhar]

Now I'm getting Compile error!

Now I'm getting Compile error!

I have just submitted the latest code you posted as-is, and got AC. Maybe you submitted the wrong file? Or forgot to comment the freopen lines?

[lichtgestalt01]

here's some input cases i tried

Input:

Code: Select all

2BBS
B2SB
BBB
BBBB
AAA
AAAA
HII
O

B
xX
b

Output:

Code: Select all

2BBS -- is not a palindrome.

B2SB -- is not a palindrome.
