Many people choose to obfuscate their email address when displaying it on the Web. One common way of doing this is by substituting the @ and . characters for their literal equivalents in brackets.
Example 1:
user_name@example.com
=> user_name [at] example [dot] com
Example 2:
af5134@borchmore.edu
=> af5134 [at] borchmore [dot] edu
Example 3:
jim.kuback@ennerman-hatano.com
=> jim [dot] kuback [at] ennerman-hatano [dot] com
Using the examples above as a guide, write a function that takes an email address string and returns the obfuscated version as a string that replaces the characters @ and . with [at] and [dot], respectively.
- Input (
email) will always be a string object. Your function should return a string. - Change only the
@and.characters. - Email addresses may contain more than one
.character. - Note the additional whitespace around the bracketed literals in the examples!
