Challenge: Filter Failure Messages

Opgave

Swipe to start coding

Imagine you have a list of system messages, and you need to extract only those containing the word "failure".

Write a program that creates a new array with only these messages and then prints them to the console.

  1. Loop through the logs array and check each message for the presence of the keyword "failure" (case-insensitive).
  2. Count how many messages contain the word "failure" and store the result in a variable count.
  3. Loop through the logs array again, and add only the messages containing "failure" into the errorLogs array.
