Write a program that reads a list of 10 integers, and outputs those integers in reverse. For coding simplicity, follow each output integer by a
space, including the last one. Then, output a newline.
Ex: If the input is:
2 4 6 8 10 12 14 16 18 20
the output is:
20 18 16 14 12 10 8 642
To achieve the above result, first read the integers into an array. Then output the array in reverse.

6.3B-2. Multiple Access protocols (2). Consider the figure below, which shows the
arrival of 6 messages for transmission at different multiple access nodes at times
t=0.1, 0.8, 1.35, 2.6, 3.9, 4.2. Each transmission requires exactly one time unit.

For the slotted ALOHA protocol, indicate which packets are successfully transmitted.
You can assume that if a packet experiences a collision, a node will not attempt a
retransmission of that packet until sometime after t=5.
