The workflow is as follows:

$1)$ Get a valid minimum $($and maximum$)$ requirement for CPU cores from the user.

$2)$ Get a valid minimum $($and maximum$)$ requirement for memory from the user.

$3)$ Access the $.$json file containing the list of EC$2$ instance types.

$4)$ Get the EC$2$ instance types as either a list of objects or as a dictionary.

$$ Converting some data types may be necessary!

$5)$ Once you have all of the EC$2$ instance types, go through them, and only print them if they met the conditions for CPU cores and memory based on what the user entered.
