Yura Barankin filled in the truth table of the function
\((\bar y \wedge (x \equiv \bar w)) \wedge (z \vee x)\). At the moment when Kostya called him out for a walk, Yura managed to fill in only a fragment of three
different rows of the table. After the walk, Yura noticed that he had not indicated which column of the table each of the variables w, x, y, z corresponds to.

Help Yura restore the table columns. Specify which column each of the variables w, x, y, z corresponds to.
In your answer, write the letters w, x, y, z in the order of their corresponding columns (first the letter corresponding to the first column; then the letter corresponding to the second column, etc.). Write the letters in the answer in a row, no separators between the letters are needed.
