Assignment: TechGiant Electronics is issuing a safety notice for certain models of its portable chargers, specifically the 'PowerPack' model from $2015$ to

$2018$ and the 'EnergyBar' model from $2016$ to $2019,$ due to potential overheating issues.

Write a program that reads the model data from input, specifically the name and then the year of production. As different versions of these models were

produced, you need to print out:

Whether the input model equals either PowerPack or EnergyBar exactly;

Whether the input model equals either PowerPack or EnergyBar ignoring case;

Whether the input model contains either substring

or EnergyBar ignoring case;

If any of these checks are true, check also the model year and print out ok if the year does not fall in the relative range or Issue notice otherwise. Your

class name should be Answer.

Take note of the sample runs, as you will need to follow the same format.
