1. Consider the shell output for this mystery function. We can see the expected input and output. Write your function for mystery1() >>> mystery1([1,2,3,4,5]) >>> list1 = [1,2,3,4,5] >>> mystery1 (list1) >>> list1 [5, 2, 3, 4, 1] >>> list2 = [17,1,82,18,19,3] >>> mystery1(list2) >>> list2 [3, 1, 82, 18, 19, 17] 2. Consider the shell output for this mystery function. We can see the expected input and output. Write your function for mystery2() >>> mystery2([1,3,5,7], 1) True >>> mystery2([1,3,5,7], 2) False >>> mystery2([1,3,5,7], 3) True >>> mystery2([1,8,17,6,42,50,3], 4) False >>> mystery2([1,8,17,6,42,50,3], 5) False >>> mystery2([1,8,17,6,42,50,3], 6) True

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
