Util Functions

The src/Utils.kt file contains some helpful methods from JetBrains that you can use in your solutions.

• The readFile(name: String) function takes in a file name and returns a List. For example:

  var count = 0
  val input = readFile("Day01").map { it.toInt() }
  for (i in 1 until input.size) {
      if (input[i] > input[i-1]) {
          count++
      }
  }
  

• The String.md5() function is an extension method on the String class that transforms a string into a md5 hash. For example:

  if ("This is a test string".md5() == "c639efc1e98762233743a75e7798dd9c") {
          // This is true
  }
