Classified

You have been hired to hide confidential information in certain documents.

Confidential information should be replaced with REDACTED.

Confidential information includes:

• The words: Peter Parker, Bruce Wayne, Clark Kent.
• Any phone number in the format: 999-999-9999.
• Any email in the format: string@string.string.
• Any four digit codes: i.e. 4444 or 1234.

For example,

Classified.redact("Spiderman is Peter Parker.")
"Spiderman is REDACTED."

Classified.redact("Batman is Bruce Wayne.")
"Batman is REDACTED."

Classified.redact("Superman is Clark Kent.")
"Superman is REDACTED."

Classified.redact("Call 555-555-5555 for the secret info.")
"Call REDACTED for the secret info"

Classified.redact("Email super@secret.shh for the private data.")
"Email REDACTED for the private data."

Classified.redact("The password is 4525")
"The password is REDACTED"

Enter your solution below.

defmodule Classified do
  @doc ~S"""
  Replaces confidential information with REDACTED in the given `string`.

  ## Examples

      iex> Classified.redact("Spiderman is Peter Parker.")
      "Spiderman is REDACTED."

      iex> Classified.redact("Call 555-555-5555 for the secret info.")
      "Call REDACTED for the secret info."

      iex> Classified.redact("Email super@secret.ssh for the private data.")
      "Email REDACTED for the private data."

      iex> Classified.redact("The password is 4525.")
      "The password is REDACTED."
