Input transforms in Angular

Angular interview exercise on Inputs & outputs, difficulty 2 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.

Give ProgressComponent a `value` input (default 0) and a `max` input (default 100), both accepting strings and converted with numberAttribute, plus a `striped` flag converted with booleanAttribute. Render <div class="bar"> showing the rounded percentage as "42%", with the class "striped" when striped.

Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
