Respuesta :

For the first question, you would just add the parenthesis to the string mutation1:

String word = "sadly";

String mutation1 = "(" + word + ")";

For the second you need the method substring from the String class:

It is defined as String.substring(begining, ending);

String name = "Smith";

String firstCharacter = name.substring(0, 1);

0 is considered the beginning of the string, then you get the next 1 characters.
