Write a recursive method to reverse a string. Explain why you would not normally use recursion to solve this problem.

What will be an ideal response?

```
public String reverse (String text)
{
String result = text;
if (text.length() > 1)
result = text.charAt(text.length()-1)
+ reverse (text.substring(0, text.length()-1));
return result;
}

```
