I have been asked a lot lately, how come it'sso different in C# to play around with strings? How come we have to doso many manipulations. We used to do this using recursions. Whilerecursions are fine, they are a main source for flaws and glitches, andI don't think you have to use them.

The string class in Java takes input throughobjects of its type only. But in the above class, if the [...]
