The nutritionist Root Escrevemos is an excellent professional in her area. One day she was interviewed live for a local newspaper. However, she was a little nervous at the time, and in such a situation, her speech is distorted a bit, repeating the end of each word after saying it. To prevent future discomfort, she asks for your help to write a program that omits the repeated part, so that the words are issued as they should be.
Write a program that, given a wrong word, it can be corrected.
There will be several test cases. Each test case is formed by a word of at most 30 characters of said wrong way. The entry ends with end of file.
For each test case, print the word properly corrected. Note the examples to check the standard, in order to properly fix all cases.
