This assignment involves creating a child thread that generates the Collatz sequence, writing it to global data it shares with the parent. When the child thread terminates, the parent will output the sequence. Your program will run similarly to the previous labs where you will pass the original number on the command line, such as

./lab3 13

You have some interesting choices for a data structure to store the sequence. One approach is to simply use an array of integer values to store the numbers in the sequence. For example, you may create a global array of the following capacity:

const int SIZE = 25; int sequence[SIZE];

The obvious issue with this approach is that static allocation may be either too large (i.e. you have created an array much larger than necessary) or too small (i.e. you have created an array that is too small to store the sequence.) A better strategy is to instead use a linked list.
