Problem Statement

Problem Statement

SMS messages are short messages sent between mobile phones. The maximum length of a single message is 160 characters, so it is often necessary to abbreviate words.

You are given a String text, and your task is to translate it to SMS language according to the following rules:

  1. Remove all punctuation symbols ('.', ',', '?' and '!').
  2. Replace all uppercase letters with their lowercase equivalents.
  3. Replace all occurrences of "and" with '&'.
  4. Replace all occurrences of "ate" with '8'.
  5. Replace all occurrences of "at" with '@'.
  6. Replace all occurrences of "you" with 'U'.
All quotes are for clarity only. The rules must be applied in the order they appear in the list. For example, "I HATE rats, and you?" will be translated to "i h8 r@s & U".

Return the resulting translation as a String.

Constraints

  • text will contain between 1 and 50 characters, inclusive.
  • text will contain only letters ('a'-'z', 'A'-'Z'), the characters ',', '.', '!', '?', and spaces (' ').
