Write n as a parameter a method writeChars takes an integer and that that writes The middle character out n characters as follows. of the output (rr*rr). should always be an asterisk If you are asked to write out an even in the middLe. number of characters, then there wil-l be two asterisks ( " <') .

The twos should surround the odd number with an equal number For example, of Lwos on either side if possible. the call: printTwos should produce 2*2*5*2*2 If the appear has an odd number of expression at the front of the expression.
