Alice, Bob, and Cindy are going on a road trip together this Christmas break! While all their other friends are vacationing in Japan and Europe, the three friends think that it's going to be more fun (and economical!) to bond by exploring the Philippines together. Coincidentally, the three of them brought the exact same kind of bag for their personal belongings. Thankfully, it should be possible to tell them apart because each bag has a name tag that says one of Alice or Bob or Cindy, corresponding to its owner. These strings are case-sensitive!

Unfortunately, the name tags have gotten a bit faded over time, so some of the letters might be a bit hard to read. You are at least assured that the length of the string on the nametag is correct. Let's help keep their vacation stress-free by writing a program that identifies the owner of the bag from a possibly unclear name tag, assuming that the owner is one of Alice or Bob or Cindy.

Input

Input consists of a single line containing a single string, corresponding to what can be read on the name tag. Each character in $$$s$$$ is either an upper or lowercase English letter, or a period . which indicates that the character is unreadable and could be any letter.

$$$$$$\begin{align*}

&\begin{array}{|l|} \hline \text{Constraints For All Subtasks} \\ \hline \text{The input string consists of $1$ to $5$ characters, each either an upper or lowercase} \\ \text{English letter or period.} \\ \hline \end{array}\\

&\begin{array}{|c|c|l|} \hline \text{Subtask} & \text{Points} & \text{Constraints} \\ \hline 1 & \mathbf{33} & \text{There is no }\mathtt{.}\text{ character in the input.} \\ \hline 2 & \mathbf{33} & \text{All characters in the input are }\mathtt{.}\text{ }\mathbf{or}\text{ the string is $1$ letter long} \\ \hline 3 & \mathbf{34} & \text{No further constraints.} \\ \hline \end{array}\\

\end{align*}$$$$$$

Output

If we assume that one of Alice or Bob or Cindy should be the owner:

  • If exactly one of their names could possibly be what is written on the nametag, output that name.
  • If there is more than one possible answer, output CAN'T TELL
  • If the name tag doesn't match with any of the three, output SOMETHING'S WRONG

You are reminded that your logic should be case sensitive.
