we all are, there's no point in anything

expected:true but was:false

means that your code returned false when the right answer is true

The sample tests are just a small selection from the actual tests. Passing the sample tests does not automatically mean that your solution is correct and will pass the "attempt" tests.

You can print to the console to see what the input was and how your code processed it. With that information, you'll be able to debug your code.
