First Equal Length Words

Write a program that reads a sequence of words, and locates the first
two words with the same length. Note that the second element of this
pair is the first word to appear with a length that has already been
seen in some previous word in the sequence.

For instance, for sequence: mouse dog crocodile bat horse the output
must be dog, bat, since it is the first pair of words with the same
length.

If no pair with the same length is found, the program output must be
"All words have different lengths".

Input

The input is a sequence of words.

Output

The output is the first pair of words with the same length.
