3. Visiting Mumbo-Jumbo. In the language of the Mumbo-Jumbo tribe, there are only two sounds: "ы" and "y". Two words mean the same thing if one can be obtained from the other by applying a certain number of the following operations: skipping consecutive sounds "ыy" or "yyыы" and adding the sounds "yы" at any position. Do the words "yыy" and "ыyы" mean the same thing?
3. Note that with any of the allowed operations, the number of letters "ы" and "y" in the word changes by the same amount. Therefore, from the word "уыу", where the number of letters "y" is greater, it is impossible to obtain the word «ыуы», where the number of letters «у» is less. Answer: no.
