Czyhd and Ghost always chat through the Internet. But IM software is unsafe , so they invented an encryption method called Czytoghophy. A message is a sentence,in other words,a message is a series of words separated by space. Ghost write a message and encrypt the message using the Czytoghophy method:
1. For each word “A1A2...An” (An is a char) in the message. Choose an integer o . The encrypted word will be “AoAo+1....AnA1A2...Ao-1” , for example the word is “czyhd” and o = 3 then we get an encrypted word “yhdcz”.
2. Encrypt the message from the first word to the last word. For each tow consecutive words (Namely A and B , and A is in front of B), remove the space between A and B and a suffix of A which is one of prefixes of B.
For example , message “hello czyhd” can be encryted into “elloh hdczy” after the first step. And then we encryted it into “ellohdczy” . We can easily know that the encrypted message is not unique for a given message .As we know , Ghost is a lazy guy . If there is a shorter encrypted text , he would never type a longer one, so he wants to know the minimum length of the encrypted message for a give message.
The data file have several cases. In each case,there is only line of message . The number of words in each case is no more than 200 and the length of each word is no more than 200.
For each case , print an integer , that is the minimum length of the encrypted message of the message given in the input case.
czyhd czyhd czyhd come out
xx make me cry
ll is a big rubbish i hate it
For 1st case , encrypted message is “ellohdczy”
For 2nd case , encrypted message is “zyhdcomeout”
For 3rd case , encrypted message is “xxakemcry”
For 3rd case , encrypted message is “llisagbishrubiehati”
We cannot encrypt “ab cd abcd” into “abcd ”.
