bstevr-assessment

A project that is created with multiple tasks

1- Alphabet Trees

  • Write a class that creates an AlphabetTree of any size or length.Add a method to the class which accepts another alphabet tree, compares the data of the two trees and prints all the unique letters within the two trees, in alphabetical order.
  • Write unit tests for the code.

2- Automated Coin Detector

  • Create a stream that randomly returns the string Real or Fake once every 3 seconds.
  • Using this stream, create an app with a scrollable list of expandable widgets that gets updated every time a new value is received.
  • For each new value, the list should be populated with a new expandable widget at the top, with only the value visible. The widget should push the existing list items down, and animate into its position; it should slide and fade in from the right.
  • If the value is Real, a sound effect (see below) should be played.
  • The title of the app should update to the last value received.
  • There should be a “Play/Pause” toggle button in the header that would pause/resume the stream. The button should animate between the two states.
  • Upon tapping one of the list items, the item should expand to show the time passed since the value was received (34s ago, 2m ago, 1h ago, etc).
  • The item should animate upon expansion/contraction and play the sound effect if the value is Real.
  • If the app is run in Debug mode, it should also print the value to the Console.

3- Speed Prototyping

  • Set a timer for 30 minutes.
  • Start the timer and try to build the screen below as accurately as possible.
  • Focus on the structure, not the content. Improvise where needed.
  • Above all, make sure the code runs when the timer is over.
