Solve: Double Char
Imported By: Geoffrey Challen
/ Version: 2021.7.0
Given a non-null
String
, return a new String
where every character in the original input is doubled.
So "The" yields "TThhee".
For this problem we're expecting only a method.
Don't define a class, include modifiers like static or public, add import statements, or add code outside the method declaration.String doubleChar(String input) {
return "";
}
