3. (Memory Game A common memory matching game played by young children is to start with a deck of cards that contain identical pairs. For example, given six cards in the deck, two might be labeled "1", two might be labeled "2 and two might be labeled "3". The cards are shuffied and placed face down on the table. The player then selects two cards that are face down, turns them face up, and if they match they are left face up. If the two cards do not match they are returned to their original position face down. The game continues in this fashion until all cards are face up or the user chooses not to continue. Write a program that plays the memory matching game. Use sixteen cards that are laid out in a 4x4 square and are labeled with pairs of numbers from 1 to 8, respectively. Your program should allow the player to specify the cards that the user would like to select through a coordinate system. For example, in the following layout: 3 All ot the cards are face down except for the pair 6 which has been located at coordinates (1,1) and (2,3). Hint: Use a 2D array for the initial arrangement of cards Lint carda [LENCT) CLENCTE (1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8):) and another 2D array that indicates if a card is face up or face down (bool faceup[LENCTH] ILENGTE] (0)). Write a function that "shuffies" the cards in the array by repeatedly (say 10000 times) selecting two cards at random and swapping them. See the sample output.
