2 Design and write your own space-invaders game. Control a gun si mouse over the enemy space-craft to zap the invaders. Invader space craft should be generated at random intervals and at random positions on the screen. Display on the screen the number of seconds remaining before the game finishes and the number of invader space-craft zapped. You might also allow different levels of difficulty. This problem gives you plenty of opportunity to experiment with sounds and graphics. Remember to use threads in this problem. ght by moving the 7M 4./ 6M A linked list is a sequence of nodes in which each node is linked or connected to the node following it. A named reference variable points to the first node in the linked list. A null reference is used to indicate the end of the linked list. Write a program to create a linked list of nonzero integer random numbers stored in disorder. Build a second linked list that contains the integers from the first linked list sorted into key order. Find the largest number in the first linked list and copy this to the second linked list. As each integer is used from the first linked list, delete it from the first linked list. Repeat the process until the first linked list is empty. Display the contents of the second linked list. (Note: You need to enter the integers in the linked list) 5. key 6M II nnlication for generating a Captcha. The captcha is a combination of
