Your task is to complete the implementation of src/components/Slides.js according to the following requirements:

  • The Slides component takes an array of slides as a prop. Each element of this array denotes a single slide and is an object with 2 properties: string title and string text.
  • On application launch, the first slide must be rendered.
  • Clicking on the "Next" button shows the next slide. This button is disabled when the current slide is the last one.
  • Clicking on the "Prev" button shows the previous slide. This button is disabled when the current slide is the first one.
  • Clicking on the "Restart" button returns to the first slide. This button is disabled when the current slide is the first one.
  • You can assume that the passed slides array contains at least one slide.

Initially, the file is filled with boilerplate code. Note the following:

  • The "Restart" button must have data-testid="button-restart".
  • The "Prev" button must have data-testid="button-prev".
  • The "Next" button must have data-testid="button-next".
  • Each slide's title must be rendered as an <h1> element with data-testid="title".
  • Each slide's text must be rendered as a <p> element with data-testid="text".

Please note that the component has the above data-testid attributes for test cases and certain classes and ids for rendering purposes. It is advised not to change them.
