The CоpyCаt gаme is plаyed in alternating turns by twо players (Player 1 and Player 2) creating sequences оf symbols. On his or her turn, a player creates a new sequence by repeating the other player’s last sequence and adding a new symbol to the end of it. For example, if during a game, one player creates the sequence: @@#&, then the next player must reproduce this sequence and add another symbol to the end such as: @@#&#. In this example, the sequence of the second player is acceptable because it repeats the previous sequence and has a single, additional symbol. For the very first turn, a player creates a sequence consisting of a single symbol. The game ends when: 1) a player does not create a single-symbol sequence on the first turn, or 2) on a subsequent turn a player does not create a sequence that is the same as the last sequence created with the addition of a single symbol. In both of these cases, the player that created an unacceptable sequence loses the game, and the other player is the winner. An Android application to play CopyCat has five Buttons and one TextView: The TextView: 1) indicates who the current player is, 2) shows the current player’s sequence as it is created, and 3) when a game has ended, indicates who the winner is. The four buttons immediately below the TextView allow players to add symbols to the sequence they are building. The “Enter” button is clicked on by a player when his or her sequence is complete. The CopyCat application starts by instructing Player 1 to proceed. As a sequence is created, the TextView displays the sequence. When the “Enter” button is clicked, the application determines if the sequence is acceptable. If the sequence is acceptable, then this process is repeated for the next player. If the sequence is not acceptable, then the game is over and the TextView indicates the winning player. You may assume that the activity_main.xml layout file has already been created as follows: You may also assume that the strings.xml resource file has already been created so that the buttons are labeled as in the above figures. Complete the CopyCat application by 1) defining the prepare method for the MainActivity class given below, and 2) defining any other classes needed by the CopyCat application. Your solution must use only a single activity. You do not need to include import statements. Any class or interface used in your solution must either: a) be defined in your solution or b) have been covered in lecture.
